How many terms are in this expression? 2xy-3x

Well,

We can distinguish between separate terms when they are joined by an addition or subtraction sign.

There are two terms in this expression: 2xy, and -3x.

When we combine like terms, we are adding/subtracting terms with "the same variable."  In this expression, we can't combine them because xy is not the same as x.

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!
