(-2) + 6 +1 = 1 + 6 + (-2)

evaluate the expression

It’s a commutative property of addition.

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!

The answer that i got was 8/3
