Answer:
y= x + 7
Step-by-step explanation:
The slope of a perpendicular line in relation to the original line will be the opposite reciprocal.
The slope of the original is -1, so the perpendicular slope will be 1.
Plug in (-4, 3) into the new equation, y = 1x + b, to find the y-intercept
3 = -4 + b
7 = b, so (0, 7) is the y-intercept
The new equation is y = x + 7
