Katie bought 4 sweaters that each cost the same amount and 1 skirt that cost $20. the items she bought cost a total of $160 before tax was added. what was the cost of each sweater?

Each sweater is $35
B/c in total it was $160
And we know that the skirt is $20
So we do 160-20 which is equal to 140
There are 4 sweaters so 140 divided by 4 which is

$35. Yayayayay

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!
