Question

What is the slope-intercept form of the equation of the line through the given point and slope?

through: (2,-2), slope = -3

Answer 1

b = 4

Explanation:

Remember y = mx+b (m = slope, b = y intercept.)

We have the slope, so, no need to solve for that.

To find the y intercept, plug in the ordered pairs to y=mx+b

-2=-3(2)+b

-2=-6+b multiply like terms

4 = b Add 6 on both sides

b = 4.
