Question

What is a standard form equation of the line through (0,-3) with slope 2/5?

Answer 1

-1 = -1

Explanation:

y = mx + b

y=-3 x=0 and m=2/5

-3 = (2/5)0 + b

Since 2/5(0) is 0, b must be -3.

So the equation is y = (2/5)x - 3

Add the slope to the given point and you get (5, -1)

-1 = (2/5) 5 - 3

-1 = 2 - 3

-1 = -1
