Given:
line y= -0.13x + 11.2
Required:
x- intercept
Solution
At the x-intercept, the value of y is zero. We have to set y into zero then solve for x.
y = -0.13x + 11.2
0 = -0.13x + 11.2
0.13x = 11.2
x = 11.2 / 0.13
x = 86.1538= 86.15
The x intercept is at ( 86.15,0)
Yes this is possible in the real-world
