In order to find the x-intercept we need to make y=0
Then we isolate the x
x y Ordered Pair type of intercept
0 0 (0,0) x-intercept
Now for the y-intercept we need to make x=0
we isolate the y
0 0 (0,0) y-intercept
ANSWER
0 0 (0,0) x-intercept
Given, y varies directly as x
So,
Where c is a constant
When y equals 5 when x is 8
So,
So, the relation between y and x
now , when x = 9
Substitute with x to find y
So, the answer is option 2. y = 45/8
