How do i find the variable for 3y+4-y=3

3y+4-y=3
combine like terms
2y +4 = 3
subtract 4 on both sides
2y = -1
divide both sides by 2
  y = -1/2

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!
