Question

a: a line passes through the point (2,8) and is parallel to y=3x+10 write the equation of the line in y=mx+b form

b: a line passes through the point (-2,-5) and is perpendicular to the line -2x+y=9 write the equation of the line in y=mx+b form

Answer 1

ANSWER:
a. y=3x+2
b. y=-1/2x-1

find the y intercepts that fit with the coordinates and for a parallel line the slope stays the same, while for a perpendicular line the slope flips and turns into the opposite symbol.
