No the way to figure it out is... use the x value in the coordinate (2, -4) x = 2 and y = -4 and plug it in and c if you get -4 for the y. That is does
-4 = -4(2) + 2
and the answer is no

To solve this question, simply put the coordinates into the equation and see if it creates a true equation.
-4 = -4(2) + 2
-4 = -8 + 2
-4 = -6
Since the two sides don't equal out, the statement is not true. The point is not on the line.

2 - No ...
-4(2) + 2 = -6, not -4
In order for the point to be on the line, the x coordinate must be properly calculated to get the y coordinate. The point would work for x = 2 if y = -6. For y = -4, then x must equal 1.5

2. NO
Plug it in and see if it works.
y = -4x+2
-4 = -4(2) + 2
-4 = -8 + 2
-4 = -6 ?
False
Therefore, (2,-4) is NOT on the line.

No. The point (2, -6) is
2007-01-15 19:44:26 · answer #5 · answered by Anonymous · 1⤊ 0⤋
for x=2
y = -4*2+2 = -6, which is different than -4, so the answer is NO

y=-4x+2 substitute -4 for x
y=-4(-4)+2
y=16+2
y=18
18â 2 so
2. NO is correct

-4=-4(2)+2
-4=-8+2
-4â -6
No because the correct point set would be (2,-6)

No
Substitute your points into the equation to validate them.

no. substitute the value of x in the equation and it should equal the value given for y. but it doesnt.
