This is an equation of a straight line, and we can easily find the the coordinates where this line intersects the axis in following ways:-

for x-axis:-
put y=0, 4x+2*0=8
4x =8
x =8/4
x =2
so intersection coordinates ate (2, 0)

for y-axis:-
put x=0, 4*0+2y=8
2y =8
y =8/2
y =4
so intersection coordinates ate (0, 4)

### Substitute 4 and -4 for x in the equations y=x+1 and 2y-2=2x. Describe the results

y = x+1
y = (4) + 1
y = 5

y = x + 1
y = (-4) + 1
y = -3

2y - 2 = 2x
2y - 2 = 2 (4)
2y - 2 = 8
2y - 2 + 2 = 8 + 2
2y = 10
2y/2 = 10/2
y = 5

2y - 2 = 2(-4)
2y - 2 = -8
2y -2 + 2 = -8 + 2
2y = -6
2y / 2 = -6 /2
y = -3

The results are the same, implying that they are the same line.

Why?

2y - 2 = 2x
2y - 2 + 2 = 2x + 2
2y = 2x + 2
divide everything by 2
y = x + 1

Good luck,

Paul

### Do i use the elimination or substitution method for the equations 16x-2y=16 and 4x=2y-8

Both should work.

16x - 2y = 16
4x - 2y = -8
-----------------
12x = 24
x = 2
y = 8

2y=4x + 8
y = 2x + 4
16x - 2(2x + 4) = 16
16x - 4x -8 = 16
12x = 24
x = 2
y = 8

Good luck.

### Mary who is sixteen years old is four times as old as her brother.How old will mary be when his twice as old as her old brother?

Let the brother's age be x:
16years for Mary = 4x years for Brother

From equation: 4x = 16
x = 4
Therefore, the brother is 4 years old.

Mary Brother
16 4
After 4 years + 4 4
20 8
After the next 4 years + 4 4
24 12

24 is twice as old as 12; therefore for the sister to be twice as old as brother she will 24years when her brother is 12 years.

Or by calculation;

If 4 is the age for the brother, when the sister is 16, and y years will pass for the to be such that the sister is twice as old as the brother, then;

16 + y = 2(4 + y)
16 + y = 8 + 2y
16 - 8 = 2y - y
8 = y
Therefore, 8 years elapse before the sister is twice as old as the brother.

Sister will be: (16 + 8) = 24years
Brother will be: (4 + 8) = 12years

### What is the y-intercept of a line with an equation 8x-8+2y=0?

8x - 8 + 2y = 0
8X + 2Y = 8
y = -4x + 4
X = 0 por y-intercept
y=mx+b
Y = 8/2 or 4
Knock knock
Who's there?

4 who?
Why yall want me to do yall's homework 4?

Do the math on that! LOL

### Find the y coordinate in the solution of -3x+y=5 if x=1

This is the process of how you would solve this.

-move the -3x over to the right hand side, so you have:
y = 5 + 3x

- since you know what x is, plug in the x which is 1:
y = 5 + 3(1)

- solve the equation
y = 5+3

y = 8, so the solution is 8.

### Solving systems of equations by elimination

Hi joanmae jmeh;

You can add these equations just like you would numbers

3x + 2y = 7
5x - 2y = 1
-----------------------
8x =8
x=1
Now plug x = 1 back into either equation and you can solve for y
Y = 2

When you add the 2 equations together the +2y and the -2y cancel
out

Hope this helps Loringh Please leave a rating for me Thks
