Isosceles triangles whise sides will exceed their base by 5 inches. if the perimeter is 100 inches, what are thw lengths of the three sides?

Isocolees means that 2 sides are equalegnth

side+side+base=perimiter=100
side is 5 more than base
s=5+b
s+s+b=100
5+b+5+b+b=100
3b+10=100
minus 10 from both sides
3b=90
divide both sides by 3
b=30
s=5+b
s=5+30
s=35

the legnsh are
35in ,35in ,30in

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!
