y = 3x - 17
Explanation:
The equation of a line in point-slope form is y = mx + c
where m represents the gradient (slope) and c , the y-intercept.
here m = 3 → partial equation is y = 3x + c
To find c , use the point (5 , -2) and substitute into the partial equation.
x = 5 , y = -2 gives : 3(5) + c = -2 → 15 + c = -2 → c = -17
