The perimeter of a rectangle is 34 inches. the length is 4 less than twice the width. what is the length of the rectangle. write a system of equations for this problem. which one of the equations below would be part of that system?

L=length, W=width. Perimeter is
P=2L+2W=34   also
L=2W-4
solve this system of 2 equations by substitution.  Put 2nd equation into first:
2(2W-4)+2W=34
4W-8+2W=34
6W=42
W=42/6
W=7
Now since L=2W-4
L=2(7)-4
L=10

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!
