The sales price of last year's hottest game is 30% off the retail price. the game sold last year for$86.00. what is the sales price?

So the retail price is 86 and it is on sale for 30% offand if it is on sale for 30% off, then u r actually paying 70%.

so we need 70% of 86turn ur percent to a decimal..." of " means multiply
0.70(86) = $ 60.20 <== sale price

Abit confused about what you mean, but i think you might be referring to slope intercept form: y = mx + bin that case b, or the y intercept is already given.(0,-1)find the slope by using the formulay2 - y1/x2 - x1the final slope will be 4/2, equivalent to 2.now your equation should look like thisy = 4/2x -1sorry if this didn’t you out!
