x - y = -2
Get the y alone on the left.
- y = -2 - x
y = 2 + x
y = x + 2
This is the slope-intercept form. y=mx+b m=slope=1 and b=intercept=2
This means that the graph has a slope of 1, so goes up one unit for each unit it goes right, and crosses the y-axis at y=2. ■

What is xy-2 when x equals 5 and y equals 4?
18
This is a graph of y equals 2x - 4?
-2
What does the math term graph mean?
it means that you are plotting the points on a graph, or XY coordinate plane
In inverse proportion x equals 2 and y equals 36 but what will y be when x equals 4?
Inverse proportion implies xy = c where c is the constant of [inverse] proportionality. x = 2 and y = 36 implies xy = 72 = c So the relationship is xy = 72 Then, if x = 4, y = 72/x = 72/4 = 18
If xz plus zy equals xy and xz equals zy then the point z is?
mid point of xy
What is xy-2 when x equals 5 and y equals 4?
18
Implicit differentiation of xy plus x equals 2?
It equals y+1
This is a graph of y equals 2x - 4?
-2
What will be the perpendicular graph to the graph of 4x-2y equals 1?
Any graph with the slope of -1/2
If xy equals x or yx equals x what is y?
xy = x ÷x y = 1
How can you translate the graph of y equals x to obtain the graph of y equals x-4 plus 2?
y equals x-4 plus 2 is the same as y = x-2. You just translate the graph of y=x, 2 units to the right, OR 2 down.
If xy plus y equals z then x equals?
xy + y = z xy = z - y (xy)/y = (z - y)/y x = (z - y)/y
What is the property for xy equals 1 xy?
That is the commutative property of equality.

If xz plus zy equals xy and xz equals zy then the point z is?
mid point of xy
Is a coordinate graph the same as a coordinate plane?
no, coordinate graph is a graph made on a coordinate plane i.e xy-plane
