Answer:
-1/4
Explanation:
The slope-intercept form is y = m x+b ,
where m is the slope and b is the y-intercept.
y = m x + b
Using the slope-intercept form, the slope is 4.
4 m = 4
The equation of a perpendicular line to
y = 4 x - 7
must have a slope that is the negative reciprocal of the original slope.
− 1 /4
