y=−17x+457

Explanation:

The slope-intercept form of the line is y = mx + c , where m represents the gradient (slope) and c, the y-intercept.

Partial equation is therefore: y=−17x+c

To find c, use (-4,7) and substitute x = -4 , y = 7 into the equation.

hence : −17×−4+c=7→47+c=7

⇒c=7−47=457 equation is y=−17x+457
