Find the x-intercept and y-intercept of each graph.?

Question

y= 2x + 3

1. x-intercept ______
2. y-intercept ______

y= 3x - 4

3. x-intercept ______
4. y-intercept ______

y= -2x + 2

5. x-intercept ______
6. y-intercept ______

y= 2x + 7

7. x-intercept ______
8. y-intercept ______

y= -x + 3

9. x-intercept ______
10. y-intercept ______

Answer 1

1) -3/2,
2) 3,
3) 4/3,
4) -4,
5) 1,
6) 2,
7) -7/2,
8) 7,
9) 3,
10) 3.

Answer 2

To find the x-intercept, set y=0 and solve for x.
1)y=2x+3
0=2x+3
2x=-3
x=-3/2
To find the y intercept, set x=0.
y=2x+3
y=2(0)+3
y=3
The other problems are similar.

Answer 3

To find the y int. set x equal to 0
To find the x int. set y equal to 0

The y intercept is where the graph crosses the y axis (the vertical axis) this only occurs when x is equal to 0.

The x intercept is where the graph crosses the x axis (horizontal) this can only occur where y is equal to 0.

I'll do one for you

y=2x+3

y int:

y=2(0)+3

y=0+3

y=3

x int.:

y=2x+3

0=2x+3

-3=2x

x=(-3/2)

So your x intercept is at (-3/2,0) and y intercept is at (0,3)

Answer 4

1. X int= -3/2
2. Y int =3
3. X int 4/3
4. Y int= -4
5. x int=1
6. y int= 2
7. x int= -7/2
8. y int =7
9 x int= 3
10. y int=3
