What is the process for finding the answer to:
0.2x - 1 = -1?

Step-by-step explanation:

0.2x - 1 = -1

first write out the problem

0.2x - 1 = -1

        +1   +1     Add 1 to both sides to remove the -1 from the same side as x

0.2x     =  0

/0.2        /0.2  Divide the number being multiplied with x to get x alone

0/0.2 = 0

x = 0         Now you have the answer.

idk im srry

step-by-step explanation:

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)
