Question

the equation of a line is y = 3. write an equation in slope-intercept form of a line parallel to y = 3 that passes through (0, 6). x = 3 x = 6 y = 3x y = 6

Answer 1

Parallel lines have equal gradients;
Gradient of line 2 is thus 0
y=c
Replacing value of y=6 gives
c=6
Equation of the line is thus y=6
