y in the first equation because y is already by itself. All you have to do is move the -3x to the other side.
Answer:
Y=-|x-2|
Step-by-step explanation:
To find which equation matches the graph, take 1 or 2 values of the line on the graph and enter the X and Y values of those points in the equations to see if they match
One good strategy is to take points that are along the axis. I'll first pick (1,-1) and will use (0,-2) to validate if one equation matches (1,-1) first.
Y=-|x|+2
for (1,-1) => -|1| + 2 = = -1 + 2 = 1 NO, should be -1
Y=-|x|-2
for (1,-1) => -|1| - 2 = = -1 - 2 = -3 NO, should be -1
Y=-|x+2|
for (1,-1) => -|1 + 2| = = -|1 + 2| = -3 NO, should be -1
Y=-|x-2|
for (1,-1) => -|1 - 2| = = -|-1 | = -1 YES
for (0,-2) => -|0 - 2| = = -|-2| = -2 YES
Hello!
"Standard form" looks like Ax + By = C.
Start by carrying out the indicated multiplication:
y + 9=-3(x-2) becomes y + 9 = -3x + 6
We want to group the x and y terms on the left and the constants on the right. Achieve this by adding 3x to both sides, obtaining: 3x + y + 9 = 6. Next, subtract 9 from both sides: 3x + y = -3.
The given equation, in standard form, is 3x + y = -3.
