Answer:
2.5in
Step-by-step explanation:
Given parameters;
Base = 4.5inches
Height = 6inches
Area = 21in²
Unknown:
b₂ = ?
Solution:
Formula for finding the area of a trapezium;
A = 
x h
Input the parameters and solve for b₂;
21 = 
x 6
21 = 3(4.5 + b₂)
21 = 13.5 + 3b₂
21 - 13.5 = 3b₂
b₂ = 2.5in
The y-intercept will be 8
And then you work out the slope by replacing the c, y and the x in y=mx+c
The y and x will be any of the coordinates above
So it will be 0=m(8)+(8)
0=8m+8
So 8m=-8
Therefore m=-1
So the y-intercept is 8 and the slope is -1
