Question

Write an equation in slope intercept form y=mx+b with points (6,7) with a slope -2

Answer 1

y = 4x -25

Answer 2

point-slope form is:
\[y-y_1=m(x-x_1) \text{ you are given } m=-2 \text{ and } (x_1,y_1)=(6,7)\]

Answer 3

plug in

Answer 4

y-y1=m(x-x1)

Answer 5

then write it in y=mx+b form by doing a little multiplication and addition

Answer 6

\[y1-y = m(x1-x)\] m = slope....y1 and x1 equal point on the line

Answer 7
