Toni is shopping for clothes at the store she buys 8 shirts for $8.00 what is the unit rate for the shirts?

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!

You need to do x2-x1,y2-y1 and divide it by 2 and you should get (1,-3)
