What is the degree of the polynomial -2xy^5 + 3x^7 -10x^3y^6 ^+8x^6+4

We have the following polynomial:
 - 2xy ^ 5 + 3x ^ 7 - 10x ^ 3y ^ 6 + 8x ^ 6 + 4
 The degree of a polynomial is the same as the degree of the term with the highest degree.
 We have then that the highest degree is in the following term:
 10x ^ 3y ^ 6 = 3 + 6 = 9
 
 The polynomial is degree 9.

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!
