Answer:
Step-by-step explanation:
To find out the m(slope) of the equation use the formula:
.
Substitute the values:
Combine the values:
Find the value of the fraction:
M is -3.
The equation so far is
To find the y intercept, substitute one pair of coordinates into the equation and solve for b:
.
We see that b =-17 so the full equation would be:
.
replace the 1st equation into the 2nd one for y
-8x-4(2x-5) = -20
-8x-8x+20 =-20
-16x+20 = -40
-16x=-40
x = 5/2 = 2.5
y = 2x-5 - 2(2.5) - 5 = 5-5 = 0
one solution (2.5,0)
5t=45
45/5=9
The answer is C
