It'll take her 15 hours.
Formula: 975= 65x
Where x represents hours
y-intercept -3
slope 1/2
is sufficient info with which to write an equation for a straight line:
y = mx + b becomes y = (1/2)x - 3.
You should check this by determining whether or not (2,-1) satisfies this equation.
130x5=650
650-104=546
546-137=409
409-154=255
255-131=124
x=124
I think the answer is True
