Question

write a slope-intercept equation for a line passing through the point (3, -3) and perpendicular to x=-5.

Answer 1

This one's easy.
Perpendicular lines have opposite reciprocal slopes.
So you already know the slope of the line will be 1/5 (the opposite reciprocal of -5)
Now, plug in (3, -3) to find b in the equation y = mx + b
(-3)= (3)(1/5) + b
--> -3 = 3/5 + b
--> -3 - 3/5 = b
--> -18/5 = b
--> y = 1/5x -18/5
