\begin{aligned} &E = 6c^2-2c-1 &F = -4c^2+7c+5 \end{aligned}


E=6c

−2c−1
F=−4c

E+F=E+F=E, plus, F, equals

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!
