Parallel line means the same slope
（8-1）/(-17-a)=(1-5)/(a+2)
so a is 18
Answer:
y-2 = -(x-2)
Step-by-step explanation:
To find the slope
m = (y2-y1)/(x2-x1) where (x1,y1) and (x2,y2) are two points on the line
= (1-3)/(4-2)
=-2/2
=-1
The point slope form is
y-y1 = m(x-x1) wher m is the slope and (x1,y1) is a point on the line
y-3 = -1(x-2)
y-2 = -(x-2)
They are the reciprocals of each other, meaning the denominator and the numerator are in switched positions
Answer:
100% true....
subtracting 19 from both sides brings you to 2x=8, so x=4
