Which table represents a linear function that has a slope of 5 and a y-intercept of 20?

erastovalidia [21]

Answer:

The first image.

x | y

-4 | 0

0 | 20 <--- When x = 0, the y value is the y-intercept.

4 | 40

8 | 60

Step-by-step explanation:

To check the slope, we can use the equation (y₂ - y₁) ÷ (x₂ - x₁) using any two pairs given. For this example, I'll use (-4, 0) and (4, 40).

x₂ y₂ x₁ y₁

(0 - 40) ÷ (-4 - 4)

(-40) ÷ (-8)

<u>Slope = 5</u>

<u></u>

What is 3/4 of 16/21? worked out please

timofeeve [1]

Of means multiplication

So

$\frac{3}{4} \sf{of} \frac{16}{21} = \frac{3}{4} \times \frac{16}{21}$

And then simplify the numerator ad denominator

= $\frac{3 \times 16}{4 \times 21} = \frac{\ 1 \times 16}{4 \times 7}$

And simplify the numerator and denominator again

= $\frac{\ 1 \times 16}{4 \times 7} = \frac{\ 1 \times 4}{1 \times 7}$

And we are finally left with the answer which is $\frac{4}{7}$
