The slope of Line M (y = 2/3x - 3) is 2/3. To figure out the slope of Line N, you need to use the equation:
m =  \frac{y_2-y_1}{x_2-x_1}

Choose any two points on the table, I chose (-2, -2) and (4, 2). Plug in and solve:
m =  \frac{2-(-2)}{4-(-2)} = \frac{2+2}{4+2} =  \frac{4}{6} =  \frac{2}{3}

So, they do indeed have the same slope of 2/3. Therefore, the answer must be A.

Answer:

119

Step-by-step explanation:

\mathrm{Supplementary\:angles\:add\:up\:to}\:180^{\circ }

\angle \:GKO \mathrm{\:is\:supplementary\:angle\:of\:} \angle \:KNL

\mathrm{So\:}\angle \:GKO+\angle \:KNL=180

\angle \:GKO+61=180

\angle \:GKO=119

3 = –(–y + 6)<br> a. –9<br> b. –3<br> c. 3<br> d. 9
Vlad1618 [11]
3 = -(-y + 6)

First, simplify brackets. / Your problem should look like: 3 = y - 6
Second, add 6 to both sides. / Your problem should look like: 3 + 6 = y
Third, simplify 3 + 6 to 9. / Your problem should look like: 9 = y
Fourth, switch sides. / Your problem should look like: y = 9

The answer is D) 9.

B. Find the value of X. Show your work, I’m not sure how to do this
Eddi Din [679]

Answer:

63°

Step-by-step explanation:

The sum of all interior angles of a triangle = 180°

Therefore:

x + 96° + 21° = 180°

x + 117 = 180

Subtract 117 from each side

x = 180 - 117

x = 63°

Luden [163]

Answer:

Non-linear equations:

y=x^2 +2x-3

3y=2^x

Step-by-step explanation:

Linear equation: y = mx + b

Therefore, a linear equation has 2 variables that have no exponents.

So the non-linear equations are:

y=x^2 +2x-3  (this is a quadratic equation - polynomial with degree 2)

3y=2^x (this is an exponential equation)
