Answer:
slope = -1
-----------------------------------------------------------------------------------------------------------------
4x+4y=8 is equivalent to y=-x+2, so -x (slope) is equivalent to -1x
Answer:
Hi there!
The answers are -9 and 5.
Step-by-step explanation:
On a number line you can either go left (towards the negative side) or right (towards the positive side) since it is asking what numbers are a distance of 7 units from -2, there are two methods you must use;
-2 + 7 means you are moving 7 units to the right and you get 5
-2 -7 means you are moving 7 units to the left and you get -9
Answer:
D. X=-3, y=4
Step-by-step explanation:
-2x+3y=18 equation 1
x=-y+1 equation 2
-2(-y+1)+3y=18 replace x value of equation 2 into equation 1
2y-2+3y=18
5y=20
y=4
solve for x by replacing y value into either equation.
x=-y+1
x=-4+1
x=-3
