Answer:
y= -2x + 7
Step-by-step explanation:
So in slope intercept y will always equal something so you start with
y= mx + b
m = slope and b = y-intercept
so in this case it would first be
y = -2x + b
and then since we have the point it passes through (-4,7) we know that the line passes through the y axis at 7 hence the y value is 7.
so you finally get
y=-2x+7
