12. If a = 1, b = 2 and c= -3, find
a) 4a'b? b) 3b²c2
e) abboca
f) ab+c bc+a ca + b​

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!
