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

Answer:

(0,15)  (5,0)

Step-by-step 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 $y=0\\3x+0=15\\x=\frac{15}{3} \\x=5$

the points that intercept the x and y axes

(0,15)  (5,0)
