For the number before x you would look for the rise over the run. in this case you can see that there is an intersection at (-2,0) and (0,1) you find the difference ox each so you have 2/1 or just 2 you can tell that the line is going up so it is positive. for the addition part look at where the y intercept is in this case it is at positive one. this makes your equation y=2x+1

3 1/2 x 23 solve this problem

pashok25 [27]

Answer:

80 1/2

Step-by-step explanation:

First, make 3 1/2 into an improper fraction so it is easier to solve.

3*2=6+1=7; 7/2

7/2*23/1

23*7=161

2*1=2

161/2=80.5 or 80 1/2

Write an equation of the form y = mx for the line shown below.

djyliett [7]

Answer:

y = -3x

Step-by-step explanation:

To get slope intercept, you divide both y values by both x values like this

$\frac{y_2 - y_1}{x_2 - x_1}$

In this case this will be $\frac{(-3 - 6)}{(1 - (-2))}$

This will become $\frac{-9}{3}$

Divide those two to get -3, and now you get your slope intercept.

Second time asking plz help. Linear or exponential. plz help me :(

7nadin3 [17]

Answer:

Exponential

Step-by-step explanation:

The change isn't constant for the volume, so it must be exponential.

Using quadratic regression, the equation is:

$y=\frac{19}{63}x^{2}-\frac{968}{105}x+\frac{3312}{35}$

Can you guys factor this problem completely for differences of squares?

a² - b² = (a - b)(a + b)

49x² - 9 = (7x)² - 3² = (7x - 3)(7x + 3)
