Find x- and y-intercepts. write ordered pairs representing the points where the line crosses the axes. 1. y=3x+6 2. y=x+1 3. x+y=6 4. 0.8x+1.6y=2.4 5. y=6x 6. 4x−2y=0 7. 3x+6y−12=0 8. y= 1/3 x− 2/3

we know that

The x-intercept is the value of x when the value of y is equal to zero

and

The y-intercept is the value of y when the value of x is equal to zero

so

case 1)

Find the y-intercept

for x=0 ------> find the value of y

The y-intercept is the point (0,6)

Find the x-intercept

for y=0 ------> find the value of x

The x-intercept is the point (-2,0)

therefore

the answer case 1) is

The ordered pairs are (0,6) and (-2,0)

case 2)

Find the y-intercept

for x=0 ------> find the value of y

The y-intercept is the point (0,1)

Find the x-intercept

for y=0 ------> find the value of x

The x-intercept is the point (-1,0)

therefore

the answer case 2) is

The ordered pairs are (0,1) and (-1,0)

case 3)

Find the y-intercept

for x=0 ------> find the value of y

The y-intercept is the point (0,6)

Find the x-intercept

for y=0 ------> find the value of x

The x-intercept is the point (6,0)

therefore

the answer case 3) is

The ordered pairs are (0,6) and (6,0)

case 4)

Find the y-intercept

for x=0 ------> find the value of y

The y-intercept is the point (0,1.5)

Find the x-intercept

for y=0 ------> find the value of x

The x-intercept is the point (3,0)

therefore

the answer case 4) is

The ordered pairs are (0,1.5) and (3,0)

case 5)

Find the y-intercept

for x=0 ------> find the value of y

The y-intercept is the point (0,0)

Find the x-intercept

for y=0 ------> find the value of x

The x-intercept is the point (0,0)

therefore

the answer case 5) is

The ordered pair is (0,0)

case 6)  

Find the y-intercept

for x=0 ------> find the value of y

The y-intercept is the point (0,0)

Find the x-intercept

for y=0 ------> find the value of x

The x-intercept is the point (0,0)

therefore

the answer case 6) is

The ordered pair is (0,0)

case 7)

Find the y-intercept

for x=0 ------> find the value of y

The y-intercept is the point (0,2)

Find the x-intercept

for y=0 ------> find the value of x

The x-intercept is the point (4,0)

therefore

the answer case 7) is

The ordered pair is (0,2) and (4,0)

case 8)  

Find the y-intercept

for x=0 ------> find the value of y

The y-intercept is the point (0,-2/3)

Find the x-intercept

for y=0 ------> find the value of x

The x-intercept is the point (2,0)

therefore

the answer case 8) is

The ordered pair is (0,-2/3) and (2,0)

step-by-step explanation:

step 1 distribute 2 to every term in the parentheses

step 2 add 10 on both sides of the equal sign
