Y=Mx+b

Rise / run between any two points = slope (m)
Where the line crosses the y axis is (yint) (b)

Slope is -1/2
Yint = -8

So the equation is y=(-1/2)x - 8

The health club is raising money through a babysitting fundraiser. On Thursday, they charged $3 per hour plus an initial fee $40

They need to babysit for 10 hours to have same money each day.

Step-by-step explanation:

On Thursday;

Charges = $3 per hour

Initial fee = $40

let x be the number of hours.

T(x) = 3x+40

On Friday;

Charges = $4 per hour

Initial fee = $30

F(x)= 4x+30

The cost will be same when;

T(x) = F(x)

$3x+40=4x+30\\40-30=4x-3x\\10=x\\x=10$

They need to babysit for 10 hours to have same money each day.
