How do I do this? -2(6-r)=4
2 answers:
To solve this, you need to isolate/get the variable "r" by itself in the equation:
-2(6 - r) = 4 Divide -2 on both sides
6 - r = -2 Subtract 6 on both sides
6 - 6 - r = -2 - 6
-r = -8 Divide -1 on both sides to get "r" by itself
(two negative signs cancel each other out and become positive)
r = 8
PROOF
-2(6 - r) = 4 Substitute/plug in 8 into "r"
-2(6 - 8) = 4
-2(-2) = 4
4 = 4

Answer <u>(assuming it can be in point-slope form)</u>:
Step-by-step explanation:
With the given information, we can use the point-slope formula, , to write the equation of the line. Substitute values for the
,
, and
in the formula to do so.
The represents the slope, so substitute
in its place. The
and
represent the x and y values of one point the line intersects, so substitute -6 for
and -8 for
. This gives the following answer and equation (just make sure to convert the double negatives into positives:
