What’s green and fluffy and comes from outer space?
1 . 2x – 4y = 8
Rewriting the standard form linear equation into slope intercept form.
-4y = -2x + 8
Dividing both sides by -4.
y = (-2/-4)x + 8/-4
y = (1/2)x - 2
The best match is A and 23.
2. 2x + 8y = - 64
Rewriting the standard form linear equation into slope intercept form.
8y = - 2x - 64
Dividing both sides by 8.
y = (-2/8)x - 64/8
y = -1/4 x - 8
The best match is N and 19.
3. -2x + 4y = 8
Rewriting the standard form linear equation into slope intercept form.
4y = 2x + 8
Dividing both sides by 4
y = (2/4)x + 8/4
y = 1/2 x + 2
The best match is M and 4.
4. 3x + 5y = -15
Rewriting the standard form linear equation into slope intercept form.
5y = - 3x - 15
Dividing both sides by 5.
y = (-3/5)x - 15/5
y = -3/5 x - 3
The best match is M and 15.
5. 12x - 3y = 3
Rewriting the standard form linear equation into slope intercept form.
-3y = -12x + 3
Dividing both sides by -3.
y = -12/-3 x + 3/-3
y = 4x - 1
The best match is L and 16.
6. y = - 8
In this case the slope is zero. Which means the rise is zero and run can be anything greater than 1. This will make a horizontal line parallel to the y-axis at the point (0 , -8).
The best match is L and 11.
7. x + 3y = 18
Rewriting the standard form linear equation into slope intercept form.
3y = -x + 18
Dividing both sides by 3.
y = -1/3 x + 18/3
y = -1/3 x + 6
The best match is T and 2.
8. -4x + 6y = -54
Rewriting the standard form linear equation into slope intercept form.
6y = - 4x - 54
Dividing both sides by 6.
y = -4/6 x - 54/6
y = -2/3 x - 9
The best match is I and 5.
9. 4x - y = - 8
Rewriting the standard form linear equation into slope intercept form.
-y = - 4x - 8
Dividing both sides by -1.
y = -4/-1 x - 8/-1
y = 4 x + 8
The best match is B and 22.
10. 2x - 10y = 20
Rewriting the standard form linear equation into slope intercept form.
-10y = -2x + 20
Dividing both sides by -10.
y = -2/-10 x + 20/-10
y = 1/5 x - 2
The best match is O and 24.
11. 6x + 9y = 9
Rewriting the standard form linear equation into slope intercept form.
9y = -6x + 9
Dividing both sides by 9.
y = -6/9 x + 9/9
y = -2/3 x + 1
The best match is E and 7.
12. 5x - 2y = 12
Rewriting the standard form linear equation into slope intercept form.
-2y = -5x + 12
Dividing both sides by -2.
y = -5/-2 x + 12/-2
y = 5/2 x - 6
The best match is A and 8.
13. 8x + 4y = 40
Rewriting the standard form linear equation into slope intercept form.
4y = -8x + 40
Dividing both sides by 4.
y = -8/4 x + 40/4
y = -2 x + 10
The best match is A and 12.
14. x + 3y = 27
Rewriting the standard form linear equation into slope intercept form.
3y = -x + 27
Dividing both sides by 3.
y = -1/3 x + 27/3
y = -1/3 x + 9
The best match is W and 2.
