Answer:
-7
Step-by-step explanation:
y=3x-7
x=0 ⇒ y= 3*0-7= -7
18.) The area of one of the triangles would be half of the area of the parallelogram, because the two triangles are congruent.
20.) The formula for the area of a parallelogram is:
A = b • h
110.5 = 13h
110.5 / 13 = 8.5
110.5 = 13 • 8.5
And because this is a measurement of the height, not the area, it is just meters (m)
So, the full answer is 8.5 m
I hope this helps!
Answer:
Step-by-step explanation:
Taking any two points, say (0,-3) and (2,-4), we can find the slope using the formula 
, which gives
.
From the graph, we can see the y-intercept is 
, so the equation of the line is .
4b-8=12
+8 +8
4b=20
Divide both sides by 4
B=5
