R=23 because its slope the formula is Y-Y/X-X
You mean what is the slope of a line parallel to the line whose slope is -2?
The answer is -2... the slopes of parallel lines are equal
I think it’s C but I’m not too sure
Answer:
7
Step-by-step explanation:
<u>9x</u> = <u>3y + 5</u>
9 9
x = 1/3y + 5/9
x - 5/9 = 1/3y + 5/9 - 5/9
x - 5/9 = 1/3y
3(x - 5/9) = 1/3y · 3
3x - 1 2/3 = y
y = 3x - 1 2/3
