Answer:
A positive slope goes up and to the right
A negative slope goes down and to the right
A slope of zero creates a flat line
Step-by-step explanation:
A positive slope goes up and to the right, because that means the graph is increasing.
A negative slope goes down and to the right, because that means the graph is decreasing.
A slope of zero creates a flat line, such as a horizontal line that never increases in the y value.

- [Right Triangles Only] tan∅ = opposite over adjacent
Step-by-step explanation:
<u>Step 1: Define</u>
We are given a right triangle. We can use trig to find the missing side length.
<u>Step 2: Identify Variables</u>
<em>POV from the angle measure</em>
Angle = 23°
Opposite Leg = 25
Adjacent Leg = <em>x</em>
<em />
<u>Step 3: Solve for </u><em><u>x</u></em>
- Substitution [tangent]: tan23° = 25/x
- Multiply <em>x</em> on both sides: xtan23° = 25
- Isolate <em>x</em>: x = 25/tan23°
- Evaluate: x = 58.8963
- Round: x ≈ 58.9
Answer:
X is 8
Step-by-step explanation:
X/8 = 2/x
Cross multiply
2x = 16
x=16/2
x=8
