Question

Which equation represents a line which a perpendicular to the line y=4x-7?​

Answer 1

Answer:

-1/4

Step-by-step 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
