Question

Find Three Equations that have an x-intercept at (-7,0)

Answer 1

x=-7

Answer 2

thts not rlly an equation

Answer 3

ok one is y=-3x+21

Answer 4

then y=-2+14

Answer 5

why not equation

Answer 6

i meant y=-2x+14

Answer 7

then y=-4x+28

Answer 8

there u go

Answer 9

y=-7 is an equation of line which is parallel to y axis

Answer 10

wait shakur

Answer 11

change my equations i give to positive at the beginning

Answer 12

y=4x+28
y=3x+21
y=2x+14

Answer 13

there u go

Answer 14

y=4x+28

To find the x-intercept, substitute in 0 for y and solve for x.

(0)=4x+28

Since x is on the right-hand side of the equation, switch the sides so it is on the left-hand side of the equation.


4x+28=0

Since 28 does not contain the variable to solve for, move it to the right-hand side of the equation by subtracting 28 from both sides.

4x=−28

Divide each term in the equation by 4.

4x4=−284

Simplify the left-hand side of the equation by canceling the common factors.

x=−284

Simplify the equation.


x=−7

To find the y-intercept, substitute in 0 for x and solve for y.

y=4(0)+28

Multiply 4 by each term inside the parentheses.


y=0+28

Solve the equation.

y=28

These are the x and y intercepts of the equation y=4x+28.

x-intercept: (−7,0)
y-intercept: (0,28)

Answer 15

284=28/4

Answer 16

4x4=4x/4

Answer 17

in my explanation

Answer 18

But I have a major problem in graphing

Answer 19

?

Answer 20

listen the x and y intercepts i showed u how to get, u just plot them on a graph, and connect the dots

Answer 21

x intercepts is when the line hits the x axis that goes from left to right

Answer 22

y intercept is when the line hits the y axis that goes up adn down in a grpah

Answer 23

just plot -7 and 28 on a graph

Answer 24

then connect

Answer 25

I will really need to work on this before my final

Answer 26

Here is some question: Find the intercepts and then graph the line

x+y=-2

Answer 27

x-intercept: (−2,0)
y-intercept: (0,−2)

Answer 28

x+y=−2

To find the x-intercept, substitute in 0 for y and solve for x.

x+(0)=−2

Remove the 0 from the polynomial; adding or subtracting 0 does not change the value of the expression.

x=−2

To find the y-intercept, substitute in 0 for x and solve for y.

(0)+y=−2

Solve the equation.


y=−2

These are the x and y intercepts of the equation x+y=−2.

x-intercept: (−2,0)
y-intercept: (0,−2)

Answer 29

here ill explain more

Answer 30

x+y=−2

To find the x-intercept, substitute in 0 for y and solve for x.

x+(0)=−2

Remove the 0 from the polynomial; adding or subtracting 0 does not change the value of the expression.


Remove the parentheses around the expression 0.

x+0=−2


Remove the 0 from the polynomial; adding or subtracting 0 does not change the value of the expression.

x=−2

x=−2

To find the y-intercept, substitute in 0 for x and solve for y.

(0)+y=−2

Solve the equation.


Remove the parentheses around the expression 0.

0+y=−2


Remove the 0 from the polynomial; adding or subtracting 0 does not change the value of the expression.

y=−2

y=−2

These are the x and y intercepts of the equation x+y=−2.

x-intercept: (−2,0)
y-intercept: (0,−2)

Answer 31

I am trying to draw the graph and see if I will get it right

Answer 32

heres the graph

Answer 33

wow are you a math instructor ,how can I be good in algebra

Answer 34

Find the intercepts and then graph the line

-4x+2y=8
