Slope of a line is the measure of its steepness. The description that compares two functions is: Option B: The line for function A is steeper.

How to get the slope intercept form of a straight line equation?

If the slope of a line is m and the y-intercept is c, then the equation of that straight line is given as:

y = mx +c

What is the equation of a line passing through two given points in 2 dimensional plane?

Suppose the given points are (x_1, y_1) and (x_2, y_2) , then the equation of the straight line joining both two points is given by

$(y - y_1) = \dfrac{y_2 - y_1}{x_2 - x_1} (x -x_1)$

For the second function, we have two pairs of points as

$(x_1, y_1) = (0,-2)\\(x_2, y_2) = (3,-1)$

Thus, the equation of the line representing the function B is

$(y - y_1) = \dfrac{y_2 - y_1}{x_2 - x_1} (x -x_1)\\\\y - (-2) = \dfrac{-1 - (-2)}{3-0}(x - 0)\\\\y + 2 = \dfrac{1}{3}x\\\\y = 0.3\overline{3}x - 2$

Since slope of line representing first function is bigger than slope of line representing second function and the bigger the slope is, the steeper it is. So line representing function A is steeper than line representing function B.

And we see that both lines have same y intercept, so the intercepts coincide on the y-axis.

Thus,

The description that compares two functions is given as

Option B: The line for function A is steeper.

The description that best compares the graph of the two function is:

The line for function A is steeper.

Step-by-step explanation:

Function: A is given by:

y=3x-2

and Function: B is given by the help of a equation:

$y=\dfrac{1}{3}x-2$

( since from the table we may see that with a increase of x by 3 units the y-value also increases by 1 units.

This means that the slope is constant and hence the function is linear.

As we see that the function passes through (0,-2) and (6,0)

Hence, the equation is given by:

$y-(-2)=\dfrac{0-(-2)}{6-0}\times (x-0)\\\\\\y+2=\dfrac{2}{6}x\\\\\\y+2=\dfrac{1}{3}x\\\\\\y=\dfrac{1}{3}x-2$

)

We know that a y-intercept is a point where x=0

y-intercept of Function A is: -2

and y-intercept of Function B is: -2

Hence, both functions have the same y-intercept.

The greater the slope the steeper the line.

Slope of function A is: 3

and slope of function B is: 1/3

As the slope of function A is more than function B.

Hence, the line for function A is steeper.

hope it

step-by-step explanation:

x^(1/6) · x^(1/6) · x^(1/6) ·x^(1/6) = x^(4/6) since we add the exponents

4/6 can be simplified to 2/3

the simplified form is x^(2/3)

First work with stencil one. use a combination of reflections, rotations, and translations to see whether stencil one will overlap with the original pattern. list the sequence of rigid transformations you used in your attempt, noting the type of transformation, the direction, the coordinates, and the displacement
