All literal equations have how many variables?

a) less than two
b) exactly two
c) more than two
d) more than one

C more than one because have you ever seen a formula that has one variable? For instance, x is not a literal equation. A=bh is a basic literal equation there is no cap on a number of variables that can be in a literal equation as long as it is more than one.

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!
