Answer:
or 3
Step-by-step explanation:
To find the slope find two coordinates and set up the equation
For the coordinates (0,2) and (2,8) y2 is 8 and y1 is 2. x2 is 2 and x1 is 0.
you have to do subtraction first. 8-2 = 6 and 2-0 = 2
Now we have the equation 
this can be simplified to 
130+45= 175
she took out $175
