Answer:
Step-by-step explanation:
Slope m = rise / run = ( - ) / ( - )
<em>1).</em> (-4,3)
(4, - 1)
m = (-1 - 3) / (4 + 4) = <em>- 1/2</em>
<em>2).</em> (-1, 1)
(2, - 5)
m = (- 5 - 1) / (2 + 1) = <em>- 2</em>
<em>3).</em> (6, 4)
(5, 4)
m = (4 - 4) / (5 - 6) = <em>0</em> (graph is horizontal line)
<em>4).</em> (1, 4)
(4, 1)
m = (1 - 4) / (4 - 1) = <em>- 1</em>
<em>5).</em> - 3/4
<em>6).</em> 4/3
<u><em>Now is your turn. You can do it!!!</em></u>
<em>7).</em> (1, 1)
(2, 2)
m = ____
<em>8).</em> ( __ , __ )
( __ , __ )
m = _____
<em>9).</em> (0, 2)
(0, 4)
m = (4 - 2) / <u><em>(0 - 0)</em></u> = undefine slope or <em>no slope</em> (graph is vertical line)
<em>10).</em>
Let's use Unitary method ~
So, the rate per hour is 32 bagels ~
So, they can prepare 480 bagels in 15 hours
With this information we can set up 2 equations:
x + y = 312 (# of tickets sold for adults + # of tickets sold to adults = 312)
12x + 5y = 2204 ( # of tickets sold for adults times $12 + # of tickets sold to adults times $5 = $2204)
Where x is how many tickets were sold to adults and y how many tickets were sold to children
Now we can solve this system of equations by substitution:
isolate y in the first equation to find its value and plug it in the second equation
x + y = 312
isolate y by subtracting x from both sides:
x - x + y = 312
y = 312 - x
Apply y = 312 - x to the second equation
12x + 5y = 2204
12x + 5( 312 - x) = 2204
12x + 1560 - 5x = 2204
7x + 1560 = 2204
Subtract 1560 from both sides to isolate x
7x + 1560 - 1560 = 2204 - 1560
7x = 644
Divide both sides by 7
7/7x = 644/7
x = 92
Now plugin 92 for x in the first equation to find the value of y
x + y = 312
92 + y = 312
subtract 92 from both sides
92 - 92 + y = 312 - 92
y = 220
x = 92, y = 220
92 tickets were sold to adults and 220 tickets were sold to children
Hope it helps :)
