What is i'm having trouble in algebra

In this problem we are solving for the variable, which is x. 

First we have to subtract 6 from both sides. (Remember: Anything done on one side of the equation must also be done on the opposite side.)

Lastly, we have to get x alone and since 3 is being multiplied by x, we must divide both sides by 3.

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!
