Y=x+7
Step-by-step explanation: because your slope is the x value and in the coordinates the y value is 7 and you put it in the form y=Mx+b
3100 because 5 in the tens column rounds up to 1 in the hundreds column
Ummmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmm
Y = x^2 + 10x - 171
y = (x - 9)(x + 19)
x - 9= 0 x + 19 = 0
x = 9 x = -19
Answer B covers all requirements... the factored form is
y= (x + 19)(x - 9)
and the zeros are -19 and 9
