Answer:
The slope is 4, and the y-intercept is -7.
Explanation:
The slope-intercept form of the equation of a line is ...
y = mx + b
where m is the slope, and b is the y-intercept.
Comparing this with the equation you are given, we see that ...
y = 4x -7
m = 4
b = -7
The slope is 4, and the y-intercept is -7.
