Step-by-step explanation:
First of all, if we want to graph this we will need to make it into slope intercept form
2x - y = 3
add y to both sides
2x = y + 3
subtract 3 from both sides
2x - 3 = y
flip the equation
y = 2x -3
we now know that the y-intercept is at (0, -3)
using that we plot the first point
The slope is 2
(this means up 2 over 1)
using that we make a line
(I'm sure you can graph it ;D)
Hope this helps :)
Is it number 6 or 8 cause I'm little bit confused
Answer:
Step-by-step explanation:
x-y=7
-3x+9y=-39
Divide the second equation by 3
-x +3y = -13
Add this to the first equation
x-y=7
-x +3y = -13
----------------------
0x +2y = -6
Divide by 2
2y/2 = -6/2
y = -3
Now find x
x-y = 7
x -(-3) = 7
x+3 = 7
Subtract 3 from each side
x = 4
(4,-3)
Or by substitution
x-y=7
solve for x
x = 7+y
-3x+9y=-39
Substitute y+7 in for x
-3(7+y) +9y = -39
Distribute
-21 -3y +9y = -39
Combine like terms
-21 +6y = -39
Add 21 to each side
6y = -18
36 inches are in one yard.
1 yard * 3 feet * 12 inches.
3*12 = 36
