Answer:
72-18=54
Step-by-step explanation:
Do good!
90. To get to this answer, you would multiply 6 X 10 and 3 X 10. You would then add the products: 60 + 30 = 90.
I will assume that we are trying to find the slope between (-9,2) and (9, 2)
The slope's equation ⇒
<u>Let's set the variables</u>:
(x1, y1) --> (-9, 2)
(x2, y2) --> (9, 2)
<u>Now let's plug them in:</u>
<u>Thus the slope of the line is 0.</u>
Hope that helps!
