Question

The slope of the line passing through P(1,4) and Q(x,1) is -3/5. What is the value of x? a. 6
b. 7
c. 9
d. 10

Answer 1

c

Answer 2

So for every 3 you go forwards in X, Y drops by 5.
Easiest way is to find the equation, imho. So -3/5x + z=Y
z = unknown

so we have 1 pt to use (P). so -3/5 x 1 (our x)= -3/5 but the Y value is 4, so the difference is 4 - (-3/5) = 4.6 so the equation is -3/5x + 4.6 = Y

so if Y=1 for the second pt, Q, plug it into the equation to get
1= -3/5x + 4.6
rearrange to get
-3.6=-3/5x
divide both sides by -3/5
x=6
