Find the intercepts for3x+y=9

Short Answer

Expert verified

The x-intercept is 3,0

The y-intercept is0,9

Step by step solution

01

Step 1. Definition 

The x-intercept is the point where a line crosses the x-axis, and the y-intercept is the point where a line crosses the y-axis.

02

Step 2. Calculating x-intercept 

To find x-intercept, let y=0

鈬�3x+0=9

鈬�x=3

So, the x-intercept is3,0

03

Step 3. Calculating y-intercept 

To find y-intercept, let x=0

鈬�30+y=9

鈬�y=9

So, the y-intercept is0,9
