Answer:
decreasing
Step-by-step explanation:
"Increasing" means the graph is going up from left to right.
"Decreasing" means the graph is going down from left to right.
"Constant" means the graph is "flat" (this is not a technical term) it is keeping the same y value, neither going up nor going down.
What can be super confusing is the
(2.2, 5) mentioned in the question. THIS IS NOT A POINT. It is an interval and points and intervals unfortunately have the same notation sometimes.
An "interval" is a section of the graph, here: FROM 2.2 not including 2.2, TO 5 not including 5. These are like the address on the x-axis. If you look at your graph at 2.2 on the x-axis, it is a peak(relative maximum) and it goes down to the right to where x is 5 where it bottoms out (relative minimum) So on that interval, from 2.2 to 5, the graph is DECREASING.
Hello :
(3, 13) <span>pair - solution because when x=3 y = 5(3)-2 = 13</span>
First, make it into slope intercept form. Subtract x form both sides
x (-x) - y = 5 (-x)
-y = -x + 5
Isolate the y. Divide -1 from both sides
(-y)/-1 = (-x + 5)/-1
y = x - 5
The slope in the form: y = mx + b, is m, which is next to the x
In this case, the m is 1
You're slope is 1
hope this helps
X-intercept: (-5,0)
Y-intercept: (0,4)
To solve for the X-Intercept, substitute 0 for y and solve for x.
To solve for the Y-Intercept, substitute 0 for x and solve for y.
