Question

What are the x- and y- intercepts for the graph of 3x+y=15

Answer 1

3x + y = 15

to find the x int, sub in 0 for y and solve for x
3x + 0 = 15
3x = 15
x = 15/3
x = 5....so the x int is (5,0)

to find the y int, sub in 0 for x and solve for y
3(0) + y = 15
y = 15....so the y int is (0,15)

Answer 2

(0,15) (5,0)

Explanation:

A line of the form
`y=mx+c` is a set of points linked together, from + infinity to -infinity.

This line, having slope, will cross at some point on the x-axis and the y-axis.

We will have to match the values ​​of x = 0 and y = 0 and find the crosses on the axes.

So if
`x=0\\3(0)+y=15\\y=15`

And if
`y=0\\3x+0=15\\x=(15)/(3) \\x=5`

the points that intercept the x and y axes

(0,15) (5,0)
