Answer 1

Answer:

Table (1)

Step-by-step explanation:

We have to find the table representing a linear function with slope = 5 and y-intercept = 20.

We know y-intercept means value of the function at x = 0,

From all the tables given in picture,

Table (1) shows the value of the function is 20 at x = 0,

So the table (1) should be the answer.

Now we will recheck the answer for the slope = 5

Since slope of a line passing through the two points $(x_1,y_1)$ and $(x_2,y_2)$ is calculated by the formula,

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

Therefore, slope of the line passing through (-4, 0) and (0, 20) will be,

m = $\frac{20-0}{0-(-4)}$

    = 5

Now we are sure that Table (1) is the answer.
