Compare the table and equation.

insens350 [35]

Answer:

The table and equation have the same slope

Step-by-step explanation:

we know that

The formula to calculate the slope between two points is equal to

$m=\frac{y2-y1}{x2-x1}$

Step 1

Find the slope of the table

we have

$A(4,12)\ B(5,15)$

Substitute the values

$m=\frac{15-12}{5-4}$

$m=\frac{3}{1}=3$

Step 2

Find the slope of the equation

we have

$y=3x$ ------> the equation represent a linear direct variation

The slope is equal to $m=3$

therefore

The table and equation have the same slope
