Answer:
Yes
Step-by-step explanation:
Given expression: 3x+9
Take 3 outside from the expression, we get,

In discussing graphs, we generally agree to move from left to right. If a line has a positive slope, then the function (and the line that represents it) is rising as we move from left to right, as in / .
Exam;ple: y=x is a straight line with the positive slope 1. As x increases, y increases by the same amount.
12x=4(x-5)
distributive property to get rid of parenthesis 12x=4x-20
subtract x from one side to get the variable on one side 8x=-20
divide 8 by -20
x=-2.5
