Find the value of x so that the line passing through the points will have the given slope: (x,6) and (10,-3) with a slope of -3/2.
let's use x as an unknown variable. you know that this amount was twice what she spent. this statement means the amount is equal to 2x. however, the amount is also 12 dollars less. so, the equation would now become 2x-12. lastly, you know that the amount she spent on jeans was 36 dollars so the equation would equal 36 dollars: 2x-12=36 hope this !
