Find each difference. (hint: If you get stuck, consider drawing a number line diagram.)
9-4=
• 4-9 =
• 9 + (-4) = 5
9-(-4) = -5
• (-4) - (-9) =
• (-9) - (-4) =

I’ll try to help.
9 - 4 = 5
4 - 9 = -5
9 + (-4) = 5
9 -(-4) = -5
(-4) - (-9) = -13
(-9) - (-4) = -13

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!
