Question

write an equation of the line that is parallel to the line y=-3x+2 and passes through the point (0,3)

Answer 1

y = 3 - 3x or y = -3x + 3

Explanation:

use form y= mx + c

m is gradient / slope

y = -3x + c (as parallel lines have the same gradient)

sub in coordinate given

3 = -3(0) + c

c = 3 (y intercept)

y = -3x + 3

or

y=3-3x
