Question

Write an equation in slope-intercept form of the line through point P(6, 7) with slope –2.

Answer 1

y = mx + b

plug in slope and the known x, y coordinates to solve for b:

7 = -2(6) + b

can you take it from here?

Answer 2

\[y-y_{1}=m(x-x_{1})\]
plug in your given values:
\[y-7=-2(x-6)\]
simplify and solve for y. You should get
\[y = -2x+19\]
