Question

Write a equation of the line described

Passes through (4,8)
Parallel to the line y=-7/4x-4

Answer 1

y=-7/4x+15

Explanation:

Parallel line so has the same gradient:

y=-7/4x+c

Substitute (4,8) into above equation

8=(-7/4 x 4)+ c

rearrange to find c

8=-7+c

c=15

New equation: y=-7/4x+15
