Answer:

The answer in the attached figure

Explanation:

we have


y=4x+2

The graph of this equation is a straight line

The domain is all real numbers

The range is all real numbers

Step 1

Find the value of y for
x=-2

Substitute the value of x in the equation and solve for y


y=4(-2)+2


y=-8+2


y=-6

The ordered pair is the point
(-2,-6)

Step 2

Find the value of y for
x=1

Substitute the value of x in the equation and solve for y


y=4(1)+2


y=4+2


y=6

The ordered pair is the point
(1,6)

Step 3

Find the value of y for
x=2

Substitute the value of x in the equation and solve for y


y=4(2)+2


y=8+2


y=10

The ordered pair is the point
(2,10)

Step 4

Plot the ordered pairs


(-2,-6)


(1,6)


(2,10)

see the attached figures
