Question

Write the equation of the line passing through the point ( - 4 , 3 ) and slope 8.

Answer 1

Explanation:

y = mx + c, where m is the gradient and c is the y-intercept of the line.

We already know that m = 8.

When x = -4, y = 3.

=> 3 = 8(-4) + c = c - 32. So c = 35.

Hence, the line equation is y = 8x + 35.
