1. Use the given information to complete the table below
Miles driven (x) Charge (y)
2. Use the slope formula to find the slope
3. Use a point and the slope to find the equation either in slope-intercept form or point slope equation
4. Plug 172 into your equation for x and calculate the value of y. The value of y is the charge.
Steps for Method 2:
1. Create two (x, y) points from the given information.
2. Find the charge per mile by finding the slope. Use the slope formula.
2. Add the charge for driving 1 mile 72 times to the cost for driving 100 miles. This will give the cost for driving 172 miles. Or, subtract the charge for driving 1 mile 52 times from the charge for driving 224 miles.
Ive gotten 34.40 as my answer i did
(72.80-48.00)/(224-100) Ive gotten 0.2 then multiplied 172 and gotten 34.40 and keep getting it wrong or its probably because i don't understand the problem in general please help me
1 answer
there is probably some base rental charge (represented by the intercept)
