The point-slope form of the equation of a straight line is:

$y-y_1=m(x-x_1)$

We have:

$m=-4\\(4;-9)\to x_1=4;\ y_1=-9$

Substitute:

$y-(-9)=-4(x-4)\\\\\boxed{y+9=-4(x-4)}$

6. a. Name a pair of equations that have exactly one point of intersection. How do you know?

True [87]

Answer:

A system of linear equations will have exactly one point of intersection, for example:

2x+y=5

-x+y=2

However, a system of linear equations with no solution will have no points of intersection, for example:

-4x+10y=6

2x-5y=3

Sorry about c. though I'm confused on how a pair of equations can have infinite points of intersection unless x or y equals all real numbers which could happen if x or y both equaled all real numbers maybe

And the point of interesection for the system of equations in the problem you attached as an image is (2,-1)
