Answer:

The four pairs of x and y values that make  the equation true are (0,2),(-1.333,0),(1,3.5), (-0.666,1).

Step-by-step explanation:

Given : Equation [tex]y=1.5x+2[/tex]

To find : Four pairs of x and y values that make  the equation true. Plot the points (x, y) on the coordinate plane.

Solution :

We take different values of x and y,

1) Take x=0,

[tex]y=1.5(0)+2=2[/tex]

The point is (0,2).

2) Take y=0,

[tex]0=1.5x+2[/tex]

[tex]x=\frac{-2}{1.5}[/tex]

[tex]x=-1.333[/tex]

The point is (-1.333,0).

3) Take x=1,

[tex]y=1.5(1)+2[/tex]

[tex]y=3.5[/tex]

The point is (1,3.5).

4) Take y=1,

[tex]1=1.5x+2[/tex]

[tex]1.5x=-1[/tex]

[tex]x=\frac{-1}{1.5}[/tex]

[tex]x=-0.666[/tex]

The point is (-0.666,1).

The four pairs of x and y values that make  the equation true are (0,2),(-1.333,0),(1,3.5), (-0.666,1).
