Best ResponseYou've already chosen the best response.1General form of all linear equations is y=mx + c where m is the gradient and c in the y intercept Rearrange the given equation in this form and you get y = 7x 5 the gradient is 7 for you. For two lines that are parallel, the gradient is the same. If you want to find the equation of a line and you know its gradient and the the point it passes through, you can use the relation yy1=m(xx1) where (x1, y1) is the point the line passes through. Just plug in the values you have y(3) = 7(x1) y+3 = 7x+7 y = 7x+4 Answer
