Answer:
y -4 = 4(x -3)
Explanation:
The slope is found using the slope formula:
m = (y2 -y1)/(x2 -x1)
m = (7 -3)/5 -4) = 4/1 = 4
The point-slope form of the equation for a line is ...
y -k = m(x -h) . . . . . . line with slope m through point (h, k)
Using the first given point, the equation is ...
y -4 = 4(x -3)
