Question

Determine the line that is parallel to y 2x+5 and passes through the point (2,3).

y = 2x + 1

y = - 1/2 x + 4

y=2x-1

y=1/2x+2​

Answer 1

Parallel lines have the same gradient so it’s the second or the fourth answer.

y = mx + c
y = 2x + c
3 = (2 x 2) + c
3 = 4 + c
3 - 4 = c
c = -1

y = 2x - 1
