Find the slope of the line shown on the graph at right.

Bumek [7]

to get the slope of a line, we only need two points, notice, the grid is using 2 numbers per line, so the point on the bottom-left is (-6,0) and the one on the upper-right is (6,4), so let's use those points.

$\bf (\stackrel{x_1}{-6}~,~\stackrel{y_1}{0})\qquad
(\stackrel{x_2}{6}~,~\stackrel{y_2}{4})
\\\\\\
slope = m\implies
\cfrac{\stackrel{rise}{ y_2- y_1}}{\stackrel{run}{ x_2- x_1}}\implies \cfrac{4-0}{6-(-6)}\implies \cfrac{4-0}{6+6}\implies \cfrac{4}{12}\implies \cfrac{1}{3}$

(8.5H)Which situation represents 1 point

<h3>The cost of purchasing baby chicks at $4.50 per chick represents proportional relationship</h3>

Solution:

in a proportional relationship, one variable is always a constant value times the other.

y = kx

Where, k is a constant

Option 1

The cost of purchasing hay for $26 a bale with a delivery charge of $30

Cost = $ 26 a bale + 30

This does not forms a proportional relationship

Option 2

The cost of purchasing baby chicks at $4.50 per chick

Let "x" be the number of chicks

Therefore,

$cost = 4.50 \times x$

Thus, this forms a proportional relationship

Option 3

The cost of purchasing fencing at $29 a linear foot with an installation fee of $300

cost = $ 29 a linear foot + 300

This does not forms a proportional relationship

Option 4

The cost of renting a backhoe for $79 per hour with a non-refundable deposit of $300

cost = $ 79 per hour + 300

This does not forms a proportional relationship

The slope of EF¯¯¯¯¯ is −52.

9966 [12]

Based on the above, the segments that are perpendicular to EF are LM and NP.

<h3>Why is the segment are LM and NP perpendicular to EF ?</h3>

Note that when two lines are perpendicular, we can say that;

M1 * M2 = -1 As M1 and M2 are known to be the slopes of the lines.

Therefore, when the the slope of EF is said to be −5/2, then one can say that the slope of the segment that is said to be perpendicular to EF will have to be equal to m1*m2=-1, m2=-1/m1, m2=-1/(-5/2) or m2=2/5.

Scenario one:

JK , if J is at (3, −2) and K is at (5, −7)

To find the slope JK, then

m=(y2-y1)/x2-x1)

m=(-7+2)/(5-3)

m=-5/2

-5/2 is not equal to 2/5

Therefore, JK is not perpendicular to EF

Scenario 2

Find GH , when G is at (6, 7) and H is at (4, 12)

To find the slope GH

m=(y2-y1)/x2-x1)

m=(12-7)/(4-6)

m=5/-2

m=-5/2

Since -5/2 is not equal to 2/5 then GH is not perpendicular to EF

Scenario 3:

Find LM , If L is at (1, 9) and M is at (6, 11)

To find the slope LM, then

m=(y2-y1)/x2-x1)

m=(11-9)/(6-1)

m=2/5

Since 2/5 is equal to 2/5

Then LM is perpendicular to EF

Scenario 4:

Find NP , if N is at (−3, 4) and P is at (−8, 2)

To find the slope NP, then

m=(y2-y1)/x2-x1)

m=(2-4)/(-8+3)

m=-2/-5

m=2/5

Since 2/5 is equal to 2/5.

Therefore, NP is perpendicular to EF

Based on the above calculations, the segments that are perpendicular to EF are LM and NP.

See correct format of question written below

The slope of EF is −5/2 .

Which segments are perpendicular to EF?

Select all the right answers please

1. JK , where J is at (3, −2) and K is at (5, −7)

2. GH , where G is at (6, 7) and H is at (4, 12)

3. LM , where L is at (1, 9) and M is at (6, 11)

4. NP , where N is at (−3, 4) and P is at (−8, 2)
