Answer:

1- click

2--trick

3- track

4-trace

Step-by-step explanation:

equation (y=x+2)       x                      y                  

y=-3+2                        -3                     -1

y=-1+2                       -1                       1

y=0+2                        0                       2

y=2+2                        2                       4

you can plot the points ( click)

<h2>equation (y=-x)               x                 y</h2>

y=-(-2)                                    -2                    2

y=0                                         0                     0

y=-1                                         1                      -1

y=-3                                        3                      -3

plot the points

<h2>equation (y=1)                                          x                   y</h2>

y=1 no matter what the value of x                     -3                      1

(-3,-1,0,2)                                                               -1                      1

                                                                                2                      1

<h2>y=1/2 x +1                    x                        y</h2><h2> y=-4/2 +1                     -4                       1</h2>

y=-2/2 +1                            -2                           0

y=1/2(0)+1                            0                           1

 y=3/2 +1                             3                          2.5

Rom4ik [11]

Answer:

(8.75, 2.5)

Step-by-step explanation:

When they ask what point (n,a) corresponds to this, they want a coordinate with an x-value of 8.75.

If we look on the graph, we can see that the a value is around 2.5 quarts of strawberries, so for our point, we will write (8.75, 2.5)
