Question

What is the equation for the line through the origin and (3, 4)

Answer 1

y = (4/3)x

Explanation:

We can use y = mx + b where b is the y-intercept and m is the slope. We can see that the slope is (4-0)/(3-0) = 4/3 and the y-intercept is at (0,0). Thus, m = 4/3 and b = 0. Substituing that in, we get that the equation is y = (4/3)x.

I hope this helps! :)
