Write the equation of a line in point-slope form that is parallel to the line y = 3x +6 and passes through the point (-5, 8).
slope = 3 (-5, 8) y - 8 = 3 (x + 5) this is point slope form y - 8 = 3x + 15 y = 3x + 23
A line that is parallel will have the same gradient. So far the equation is y=3x+c. To work out c, you substitute in your coordinate it passes through. 8=(3 times -5)+c 8=-15+c C= -7 So the answer is y=3x-7. Hope that helps!
