What is the error? PLEASE PLEASE HELP

The right answer is 0 < m - 3/4 < 3

Step-by-step explanation:

3/4 < m < 3 3/4

The error is 3/4, m, and 3 3/4 has to substract 3/4

3/4 - 3/4 < m - 3/4 < 3 3/4 - 3/4

The right answer is

0 < m - 3/4 < 3

c. y = 1/4 x + 5

step-by-step explanation:

first, put the equation of the line on the graph into slope-intercept form

(y = mx + b):   y = -4x + 8

second, a perpendicular line has to have "an opposite/reciprocal slope" to the original slope. so, find the "m" value in your original equation (it's -4, right? )

original slope: m = -4   perpendicular slope: change the sign to its opposite and find the reciprocal ("flip" the number)

new slope is now positive (b/c the original slope was negative 4), and it's 1/4 (not the original slope of 4 or 4/1)
