What is a solution for the equation 2x-y=5

Y = 2x - 5
You would subtract -2x from both sides, and then divide -y by both sides

2x - y = 5 -2x. -2x -y = 5 - 2x --- -1. -1 y = 5 + 2x Then you would plug in y= 5+2x into the regular equation. So: 2x - ( 5 + 2x) = 5 2x - 5 - 4x = 5 -2x - 5 = 5 +5. +5 -2x = 10 -2. -2 x = -5 Then you would solve for y

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!
