Number 1 is D, and number 2 is B.
A
to calculate the slope m use the gradient formula
m = ( y₂ - y₁ ) / (x₂ - x₁ )
with (x₁, y₁ ) = (7, - 2 ) and (x₂, y₂ ) = (- 1, - 5 )
m = = = → A

64.80xs.5=$162 $162-20=$142 142x1.09=$154.78 The RacerZ costs $142 and the Swiftee costs $154.78
Get a common denominator.
9/10
4/5 = 8/10
