$y = m x + + c$ $y=mx++c$ is the general equation with $m$ $m$ as the slope

$y = 4 x + c$ $y=4x+c$ now put (-3,7) into the equation to find the y intercept

$7 = 4 \times - 3 + c$ $7=4xx-3+c$

$7 = - 12 + c$ $7=-12+c$

$c = 19$ $c=19$

This gives $y = 4 x + 19$ $y=4x+19$

$y - 7 = 4 (x + 3)$ $y-7=4(x+3)$

Explanation:

$the equation of a line in point-slope form$ $"the equation of a line in "color(blue)"point-slope form"$ is.

$∙ x y - b = m (x - a)$ $•color(white)(x)y-b=m(x-a)$

$where m is the slope and (a, b) a point on the line$ $"where m is the slope and "(a,b)" a point on the line"$

$here m = 4 and (a, b) = (- 3, 7)$ $"here "m=4" and "(a,b)=(-3,7)$

$y - 7 = 4 (x + 3) \leftarrow in point-slope form$ $y-7=4(x+3)larrcolor(red)"in point-slope form"$
