Find the slope and y-intercept for the two linear functions. Linear Functions Identify the slope of the line given in the table:
Natalija [7]

ANSWER

See explanation

EXPLANATION

The table contains these two points (-4,-3) and (2,-4.5)

The slope of this line is given by;

m =  \frac{rise}{run}

m =  \frac{ - 4.5 -  - 3}{2 -  - 4}  =  \frac{ -  1.5}{6}

m =  -  \frac{1}{4}

The y-intercept can be obtained by finding the equation of the line in the form:

y = mx + c

We plug in the slope and the point (-4,-3) to find c.

This implies that,

- 3 =  -  \frac{1}{4}  \times  - 4 + c

- 3 = 1 + c

c =  - 3 - 1 =  - 4

Hence the y-intercept is -4.

The given line is

y =  \frac{3}{2} x + 1

This is already in the slope intercept form:

The slope is

m =  \frac{3}{2}

The y-intercept is c=1

29 mint plants and 29 other herb plants at the garden center. Considering this data, how many of the next 62 herb plants stocked
spin [16.1K]

Answer: 31 mint plants

Step-by-step explanation:

         We will have mint plants over total plants:

29/29+29 = 29/58 = 1/2

         Now, we will multiply 62 by 1/2 to guess how many mint plants will be stocked.

62* 1/2 = 31

  We should expect about 31 plants of the total plants to be mint plants.

Who can help with geometry
Kay [80]

Answer:

h = 21.5cm.

Step-by-step explanation:

<em>Step one:</em> Simplify the volume.

220.16 x (pi) = 691.65cm^3.

<em>Step two:</em> Isolate h.

Cylinder volume equation: V = (pi)(r^2)(h), where r is the radius and h is the height.

Divide out the pi and r^2 on both sides to isolate h and move the equation to V/(pi)(r^2) = h.

<em>Step three:</em> Solve for h.

691.65/(pi)(3.2^2) = 21.5cm rounded to the nearest tenths place.

To illustrate this, please check the diagram below.

A line through which two points would be parallel to a line with a slope of 3/4?
irga5000 [103]

Answer:

F. (0, 5) and (-4, 2)

Step-by-step explanation:

We need to calculate the slope of each of the given sets of points until we find the set associated with a slope of 3/4:

F. (0,5) and (-4,2)  As we go from (-4, 2) to (0,5), x increases by 4 and y increases by 3, so the slope is m = rise / run = 3/4.  This is the line with slope 3/4.
