X/2=1.2
solve for x and check.

x = 2.4

You want to get x by itself, so you need to get rid of the division on the left side of the equals sign. The way to undo division is to multiply. So, multiply both sides of the equation by 2. This gives you x = 2.4, so now you have your answer.

Now, since the problem wants us to check our answer, we just put 2.4 back into the equation as x. This gives us 2.4 / 2 = 1.2. Now, we just simplify to see if the equation is true. If it is true, the answer is correct. 2.4 divided by 2 is 1.2, so 1.2 = 1.2, which means our answer is correct.

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)
