A:
Answer:y = -2y=[tex]\frac{4}{5}[/tex]x - 5Step-by-step explanation:Let y=mx + cSo f(4)=-2this gives, -2=4m+c -----------eq 1Also f(0)=-2This gives -2=c. --------------eq2Putting value of c in equation in eq1 we get m=0.So y=-2.For the third question,let y=mx + cf(0)=-5this gives, c = -5.f(5)= -1this gives -1 =5m -5. => 4=5m => m=[tex]\frac{4}{5}[/tex] So y=[tex]\frac{4}{5}[/tex]x - 5
