Step-by-step explanation:
Point-slope is the general form y-y₁=m(x-x₁) for linear equations. It emphasizes the slope of the line and a point on the line (that is not the y-intercept).
Are you missing something?
2xy=7
5xy=9
does not have a solution.
If you mean
2x+y=7
5x+y=9
please say so.
Simplifying-
(6d^2)(-7d)=
= -(42d^2)(d)
=-42d^3
y=-1/2x-4
I could be wrong. Not my strong subject.
