Problem
Find the area enclosed between y = x² and y = 2x in the first quadrant.
1
Find the points of intersection
Set the curves equal: x² = 2x → x(x - 2) = 0, so x = 0 and x = 2.
2
Identify which curve is on top
On (0, 2), 2x > x², so y = 2x is the upper curve.
3
Set up the area integral
A = ∫₀² (2x - x²) dx
4
Integrate term-by-term
A = [ x² - x³/3 ]₀²
Final Answer
A = 4/3 sq. units
Quick Answer
What is the AskSia Slope-Intercept Form Solver?
AskSia's Slope Intercept Form Solver is an AI tool that writes the equation of a line in slope-intercept form (y = mx + b) from any starting point. AskSia accepts two points, a point with a slope, the slope and y-intercept directly, standard form (Ax + By = C), or point-slope form (y minus y1 = m(x minus x1)). Each conversion is shown step-by-step with slope and y-intercept labeled, and the line is graphed for visual confirmation.

Why AskSia Solver
Every input. One y = mx + b.
Two points, a point and a slope, or another form. AskSia converts to slope-intercept with the algebra shown and labels m and b explicitly.
From point and slope
Plug the slope and one point into y = mx + b to find b directly: b = y minus mx. The arithmetic is shown.
Point and slope
From standard form
Convert Ax + By = C to y = mx + b by isolating y: subtract Ax from both sides, divide by B. The slope becomes minus A over B and the y-intercept becomes C over B.
From standard
From point-slope form
Distribute the slope across the parentheses, then add y1 to both sides. AskSia shows the distribution and simplification.
From point-slope
Identify slope and y-intercept
Slope m is the coefficient of x and y-intercept b is the constant term. AskSia labels both explicitly and shows the y-intercept point (0, b) on the graph.

Auto-generated graph with the y-intercept marked, the slope shown as rise over run, and a second point labeled. Useful for checking the form visually.

FAQ
Frequently asked questions.
What does slope-intercept form mean?
Slope-intercept form is the equation of a line written as y = mx + b, where m is the slope (rise over run) and b is the y-intercept (the value of y when x = 0). It is the form most useful for graphing because both pieces of information needed to draw the line (start at the y-intercept, then go up m for every step right) are visible directly in the equation.
How does AskSia find slope from two points?
AskSia uses the slope formula m = (y2 minus y1) over (x2 minus x1). The substitution is shown with explicit labels for which point is (x1, y1) and which is (x2, y2). After computing m, AskSia plugs one point into y = mx + b to solve for b.
Can AskSia convert standard form to slope-intercept?
Yes. From Ax + By = C, AskSia subtracts Ax from both sides to get By = minus Ax + C, then divides by B to get y = minus (A/B)x + (C/B). The slope is minus A over B and the y-intercept is C over B. The step-by-step algebra is shown.
Can AskSia find the equation of a line parallel or perpendicular to a given line?
Yes. For a parallel line, AskSia uses the same slope as the given line. For a perpendicular line, the slope is the negative reciprocal. Either way, AskSia substitutes the given point into y = mx + b to find the new y-intercept, then writes the equation in slope-intercept form.
How accurate is AskSia?
AskSia is engineered for accuracy on standard high school and college coursework. Accuracy comes from subject-specialized models, a symbolic verification pass that catches arithmetic errors, and a self-check step that re-derives the answer before showing it to you.
Can I get practice problems and flashcards?
Yes. After any solve, ask Sia to generate similar practice problems at SAT, ACT, AP, IB, or college difficulty, or build a flashcard set on the underlying concept in one tap. Useful for exam prep and spaced repetition before a quiz, midterm, or final.
How much does AskSia cost?
AskSia has a free plan that includes daily solves across all subjects. AskSia Pro and Super include unlimited solves, advanced subjects, the full AI tutor companion, exports, and priority response speed. See pricing for details.
