Answer:
b=0
Step-by-step explanation:
y=mx+b
(0,0) means x=0 and y=o
m=2
Make b the subject of formula
b=y-mx
b=0-2(0)
b=0-0
b=0
Therefore,0=2(0)+0
=0
Therefore the equation of the slope is 0
Step 1. Add 72 to both sides
5y = 7 + 5x + 72
Step 2. Simplify 7 + 5x + 72 to 5x + 79
5y = 5x + 79
Step 3. Divide both sides by 5
y = 5x + 79/5
Hi!
<h3>To do this, put the values in the equation. </h3>
-2 * 2 + 4 * 5 = -16
<h3>Solve</h3>
-4 + 20 = -16
<u>16 = -16</u>
<h2>(2,5) is not a solution of -2x+4y=-16</h2>
Hope this helps! :)

Answer:
C. 62
Step-by-step explanation:
because all of the angles must = to 180 degrees and the 2 bottom must be equivalent so 62+62+56=180
