What is the slope, m, and the y-intercept of the line that is graphed below? On a coordinate plane, a line goes through points (
salantis [7]

Answer:

m = 1; (0, 3) is the correct answer.

Step-by-step explanation:

The general equation of a line is given by:

y=mx+c

where, m is the slope of line

c is the y-intercept and

(x,y) are the points from where the line passes.

We are given that the line passes through 2 points (-3,0) and (0,3).

Putting the values of (x,y) in the equation of line.

Putting (0,3):

3 = m \times 0 + c\\\Rightarrow c =3

So, y-intercept is (0,3).

Hence, equation of line becomes:

y = mx + 3

Putting (-3,0) in y = mx + 3:

0 = m(-3) +3\\\Rightarrow 3m = 3\\\Rightarrow m =1

So, the equation of line becomes:

y = x +3

Please find attached graph.

m = 1; y intercept (0, 3) is the correct answer.

Alexa says that the pattern with the expression 5n+3 will not contain the term 82. Is she right? Explain your answer.
kolbaska11 [484]

Answer:

correct

Step-by-step explanation:

She is correct.

For any integer, n, 5n is a multiple of 5.

5n + 3 is 3 more than a multiple of 5.

Start with 82. Subtract 3. Now you have 79.

79 is not a multiple of 5, so 5n + 3 will not contain the term 82.

In right triangle ABC, shown below, cos C 9√130/9 find AC.
Afina-wow [57]

Answer:

<h2>AC = 9</h2>

Step-by-step explanation:

cosine=\dfrac{adjacent}{hypotenuse}\\\\\text{We have:}\\\\\cos C=\dfrac{9\sqrt{130}}{130}\\\\adjacent=AC\\\\hypotenuse=\sqrt{130}\\\\\text{Substitute:}\\\\\dfrac{9\sqrt{130}}{130}=\dfrac{AC}{\sqrt{130}}\qquad\text{cross multiply}\\\\130AC=(9\sqrt{130})(\sqrt{130})\qquad\text{use}\ \sqrt{a}\cdot\sqrt{a}=a\\\\130AC=(9)(130)\qquad\text{divide both sides by 130}\\\\\dfrac{130AC}{130}=\dfrac{(9)(130)}{130}\\\\AC=9
