Question

How do you write the equation in point slope form given (5,-2) m=3?

Answer 1

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
