Because 2 squares equal a meter u have to do four up down one. (Front elevation)
Then just four by one square on second row down(side elevation)
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!
Answer:
9
Step-by-step explanation:
Plug in -2 for x, and -1 for y, and solve:
3x - 4y + 11
3(-2) - 4(-1) + 11
Remember to follow PEMDAS. First, multiply. Remember, that when you multiply:
2 positive signs will result in a positive answer.
1 positive & 1 negative will result in a negative answer.
2 negative will result in a positive answer.
3 * -2 = -6
-4 * -1 = 4
-6 + 4 + 11 = 9
9 is your answer.
