Find the degree of the polynomial 9x^3 y6 + 2.5xy + x^2 .

The degree of the polynomial is 9 ( not determined by the first number)
The degree of a polynomial is the highest exponent.
Here the highest exponent is 6 but since y is not a term on its own, you add the exponent of the term together.

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!
