Which expression is a trinomial? x + y – 13 4xyz

X+y-14
Trinomial
Tri=3
If it has a sign (+ or -) count like a monomial. If you have +x+y-14 that’s a TRInomial

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!
