Write an equation that represents the line.
Use exact numbers.

Step-by-step explanation:

Finding slope

Slope-intercept formula: y = mx + b

Two good points on the graph:

(2, -2)

(-3, -6)

Two-point slope formula:

Plug these points into the graph:

                          solve

                             simplify

                               a negative divided by a negative is a positive

m = 4/5

Finding y-intercept

The y-intercept is the point where the line of the graph goes through the y-axis. And when x is 0. In this graph, we have a point in between -3 and -4, but closer to -4. But is nearer to -4, so we will approximate:

b = (0, -3 3/5)

The equation

The last step is setting up the equation. We are using slope-intercept: y= mx + b

Plugin the values for m and b

y = mx + b

y = 4/5x - 3 3/5 (note that since it is negative, which has a minus sign, it replaces the +.

d. 9

step-by-step explanation:

in the table given in the picture, x is the input of the function and f(x) is the output on the given input. in the given table, it can be read as the value of function at -3 is it's respective value of f(x) which is -9.

as we have to find the value of f(3), we will see that what is the value of output on input 3. we can see in the table that the output value at x=3 is 9.

so, option d is the correct answer ..

19.side- angle- side

20. angle- side- angle
