Find the equation of the line given the following conditions.
6. Passing through (-8, -10) and parallel to the line whose equation is y = -4x + 3
7. Passing through (2, -3) and perpendicular to the line whose equation is y = (1/5) x + 6
8. Passing through (5, -9) and perpendicular to the line whose equation is x + 7y – 12 = 0
Y = mx+ b. Is equation of a line. M is slope....then sub in the point given to find b
First one slope is -4
Second one slope is -1/(1/5)=-5
Third one slope is -1/(-1/7)=7
