Answer:

y= -\frac{1}{2} x-3

Step-by-step explanation:

Slope intercept form :

y = mx + b

m is the slope

b is the y-intercept

Let's look for m, use the formula \frac{(y_{1}-y_{2} ) }{(x_{1} -x_{2} )} to determine it.

\frac{-9 - (-2)}{12 - (-2)} = -\frac{1}{2}

y = -\frac{1}{2}x+b

Now find b, we simply need to plug in one of our coordinates to get our answer.

(12, -9)

-9=-\frac{1}{2} (12)+b

Solve for b :

-9 = -6 + b

-3 = b

b = -3

Our slope intercept is :

y = -\frac{1}{2}x - 3

1) Graph by making a<br> table.<br> y=1/2x+2
nadya68 [22]

Answer:

Below.

Step-by-step explanation:

You can use any 4 x values, so we could have:

- 2  0  2  4

Now find the corresponding y values by substitution in the equation:

For x = -2, y = 1/2 *-2 + 2 = 1.

For x = 0, y = 1/2 * 0 + 2 = 2.

For x = 2 , y = 1/2* 2 + 2 = 3.

For x =  4 , y = 1/2 * 4 + 2 = 4.

So the table is:

-2   0    2   4

1    2    3   4

You then plot the points (-2, 1), (0, 2), (2, 3) AND (4, 4) on the grid  and draw a line through them The graph will be a straight line.
