Given points are (6,7) and (2,-1). Now we have to find the equation of line that doesn't passes through these two points.
Since choices are missing to I will find equation of line passing through those points first then any choice which is not equivalent or same as the obtained equation will be the answer.
Slope is given by formula :
Now plug m=2 and any point say (2,-1) into y=mx+b
-1=2*2+b
-1=4+b
-5=b
plug m=2 and y=-5 into y=mx+b
So the line passing through given points is y=2x-5
Hence any choice which is not equivalent or same as the obtained equation y=2x-5 will be the answer.
Answer:
a = 1
Step-by-step explanation:
It is an isosceles triangle (angle 45°, 90°, 45°), therefore a = b
