Sally has $21.40 in dimes and quarters. There are a total of 200 coins. How many of each kind of coin does Sally have? Solving by Systems - What is x and y?
( x = dimes ) ( y = quarters )

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 are dumb you will drop out of high school
