C
A line with undefined slope is a vertical line parallel to the y-axis, passing through all points with the same x-coordinate.
For this reason it's equation is x = c
where c is the value of the x-coordinate the line passes through
For (- 3, 5 ) the x-coordinate is - 3, hence
x = - 3 → is the equation of the line
You may write them separating the units and tens digits, and then use FOIL to add 4 easy tems. For example, let's compute
:

I’m not sure the answer but go into a webpage called Desmos and it will show you
Answer with Step-by-step explanation:
We are given that
O(0,0),P(3,-1) and Q(2,3) on the coordinate plane.
Mark point O(0,0), P(3,-1) and Q(2,3) on the graph and then join OP,PQ and OQ.
b.We have to find OP and OQ are perpendicular or not.
Slope-formula:
By using the formula
Slope of OP=
Slope of OQ=
When two lines are perpendicular then
Slope of one line=
Slope of line OP
Hence, line OP and OQ are not perpendicular.
