Y= -2x+3
-2 is the slope which is given, and 3 is the y intercept which is also given, so plug those numbers in y=Mx+b to make your equation
Answer:
64.84 square cm
Step-by-step explanation:

Answer:
The values of r = -3/2 ,7
Step-by-step explanation:
2r2 - 11r - 21 = 0.
The is a quadratic equation in the form
2r²-11r -21= 0
Let's determine the value of r using factorization method
2r² -14r +3r -21= 0.
2r(r-7)+3(r-7)= 0
(2r+3)(r-7)= 0
2r+3= 0
2r= -3
r= -3/2
And
r-7= 0
r= 7
The values of r = -3/2 ,7
