Solve a/ -6 + 8 = 12. a=?

A=10 combine like terms which gives you a+2=12 then subtract two from both sides which gives you 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!

Ithink it's b sorry if i'm wrong
