Answer:
A. y + 1 = -2(x-2)
Step-by-step explanation:
point-slope equation is : y - y1 = m (x -x1)
remember m= slope value
the given point is (2, -1) therefore we can substitute the values in:
y + 1 = m(x -2)
now to make sure our answer is complete we will solve for the slope:
looking back at the graph, the y-intercept value is 3, therefore we have a point of (0,3) and (2, -1)
with any two points you can determine a slope.
y2 - y1 / x2 - x1
therefore :
-1 -3 / 2 - 0
-4 / 2 = -2
therefore our m value is -2
this makes the completed point-slope equation:
y + 1 = -2 (x - 2) or A

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.
The answer is AA Similarity Postulate.
