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 y = mx + b Solver?
AskSia's Y Mx B Solver is an AI tool that writes the equation of a line in y = mx + b form from any input. AskSia accepts two points, a point with a slope, the slope and y-intercept, standard form (Ax + By = C), or point-slope form. Slope m and y-intercept b are identified explicitly, the algebra is shown step-by-step, and the line is graphed with both labeled.

Why AskSia Solver
Find m. Find b. Write y = mx + b.
Two points, a point and slope, another form. AskSia computes m and b, writes the equation, and graphs the line.
b by substitution
Once m is found, plug one point and m into y = mx + b and solve for b. AskSia shows the arithmetic explicitly.
Find b
From standard form
From Ax + By = C, isolate y to get y = minus (A/B)x + (C/B). Slope is minus A over B; y-intercept is C over B.
From standard
From point-slope
Distribute the slope across (x minus x1), then move the constant to the other side. AskSia shows distribution and simplification.
From point-slope
Identify m and b in y = mx + b
Given an equation already in y = mx + b form, AskSia labels m and b and marks the y-intercept on the graph.

Step 02
Watch Sia compute m and b
Slope first, then y-intercept by substitution. Each step labeled with a plain-English reason.
1
Set curves equal
x² = 2x → x = 0, x = 2
2
Set up the integral
A = ∫₀² (2x - x²) dx
3
Evaluate
A = [x² - x³/3]₀² = 4/3

FAQ
Frequently asked questions.
What is y = mx + b?
y = mx + b is the slope-intercept form of a linear equation in two variables. The letter m is the slope of the line (rise over run, or the change in y per unit change in x). The letter b is the y-intercept, which is the value of y when x = 0, or the point where the line crosses the y-axis. The form is useful for graphing because both pieces of information appear directly in the equation.
How does AskSia find b once m is known?
AskSia plugs one of the given points into y = mx + b with the known slope m and solves for b. For example, with slope m = 2 and point (3, 7): 7 = 2 times 3 + b becomes 7 = 6 + b, so b = 1. The substitution and simplification are shown explicitly.
Can AskSia write y = mx + b from a graph?
Yes. Snap a photo of a graph and AskSia identifies the y-intercept directly from where the line crosses the y-axis, and computes the slope from two clearly marked grid points on the line. The equation is written with m and b labeled and the graph is regenerated with both marked.
What if a line has no y-intercept or is vertical?
Vertical lines have an undefined slope and cannot be written in y = mx + b form. They are written as x = c, where c is the x-coordinate of every point on the line. AskSia recognizes vertical lines and returns the x = c form with an explanation. Lines with slope zero are horizontal and have the form y = b.
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.
