The graph of a linear function passes through points a(-2, 5) and b(4, -4). what is the rate of change of the graph?

When using the the slope formula the equation would be

-4-5= -9

4- -2=6

You divide and u get 1.5 which is also known as 1 and 1/2

6.9

step-by-step explanation:

simple math really

6 1/2 times 0.6 = 3.9

but if you are just doing 6 and not 6 1/2 then the answer is 3.6

let y equal to

the total fare and x is the mile of taxi ride. so the equation is

y = 0.55x + 1.75

since susie has

$10 to spend for a taxi cab, so he can have

10 = 0.55x +

1.75

x = 15 miles of

taxi ride

so the system of

inequality is

10 < 0.55x +

1.75

x > 2
