Answer:
y= 2x +8
Step-by-step explanation:
y= 2x+3
gradient of given line = 2
(coefficient of x term when the coefficient of y is 1)
Parallel lines have the same gradient.
Hence gradient of the unknown line is 2.
y= 2x +c
To find the value of c, substitute a coordinate.
When x= 7, y=6,
6= 2(7) +c
6= 14 +c
c= 6-14
c= -8
Thus, the equation of the line is y= 2x +8.
