Answer:
it is a whole number there's something wrong in the question
Step-by-step explanation:
Y= -5/3x + 2
To find slope:
-8-7 / 6 - (-3) = -5/3
Plug in x and y from one of the points to the equation to find b
7 = -5/3 (-3) + b
B = 2
Put it all together:
y = -5/3x + 2
y = x^2 + 2x...eqn 1
y = 3x + 20...eqn 2
subst for y in eqn 1...
=> x^2 +2x = 3x +20
=> x^2 - x - 20 =0
=> (x-5) (x+4) =0
=> x = 5 or -4
for x =5, y = 35 (sub for x in eqn 1 or 2)
for x = -4, y = 8 (sub for x in eqn 1 or 2)
