Exercise 25 Page 133

How do you calculate and write the x-intercept and y-intercept?

x-intercept: (8,0)
y-intercept: (0,2)
Explanation: Misinterpretation of how an intercept is written.

Practice makes perfect

Let's look at the given linear equation. 3x+12y=24 The equation is written in standard form, and it represents a straight line on the plane. In the given solution both intercepts were calculated in a correct manner, but they were not written properly. With any non-horizontal linear function, the x-intercept has y=0 and the y-intercept has x=0. We must write the correct answer as two points. &x-intercept:(8,0) &y-intercept:(0,2)
