Madison and Lucas went to the fair. Madison rode 8 rides and spent $20. Lucas rode 5 rides and spent $17. Write a linear equation, in slope-intercept form, that models the cost y of one person going on x rides. You can write the equation in any form.
1. Write an ordered pair representing Madison's data. Remember: ordered pairs look like (2,6)
2. Write an ordered pair representing Lucas's data. Remember: ordered pairs look like (2,6)
3. Calculate the slope
4. Write the Equation of the line
Answers
Answer:
first solve for x
8x=20
x=2.5
5x=17
x=3.4
then your equations
Madison: y=2.5x
Lucas: y=3.4x
then your ordered pairs
Madison: (4,10)
Lucas:(3,10.2)
then your slope
Madison-2.5
Lucas-3.4

Find the measure of the angle indicated.
Answers
Answer:
60 degrees.
Step-by-step explanation:
Do you see those red points on the lines? Those red arrows indicate that the lines are parallel, meaning, when there's a line crossing through two parallel lines, are vertical and adjacent angles are the same.
In this case, 11x-6 is equal to 10x.
11x-6 = 10x
-6 = -1x
divide -x both sides, you get x = 6.
Now you know that 11x - 6 = 60, because 11x - 6 = 10x, and since x = 6, 10x = 60.
---------------------------------------------------------------------------------------------------------
Since 10x is on a straight line, the angle next to it adds up to 180, so...
10x + y = 180.
We know that 10x = 60, so 60 + y = 180.
subtract both sides by 60, you get y = 120.
Now, you solved the whole graph.

How do you solve for the slope of a graph that isn't straight? How would I solve the slope for this?
Answers
9514 1404 393
Answer:
use the slope formula
Step-by-step explanation:
Usually, you are asked for an average slope over some interval. The slope is calculated on that interval the same as it would be if you were given two points, one at each end of the interval.
m = (y2 -y1)/(x2 -x1)
For example, if you wanted to know the slope on the interval [1, 2] hours, the points you would use would be ...
(hours, miles) = (1, 25) and (2, 75)
The corresponding slope on that interval is ...
m = (75 -25)/(2 -1) = 50 . . . . miles per hour
__
You can identify four (4) regions on this graph in which the slope is constant:
(0, 1) . . . slope is 25 mph
(1, 2) . . . slope is 50 mph, as computed above
(2, 3) . . . slope is 0 (the rider has stopped)
(3, 5) . . . slope is 25 mph
Over different intervals, you need to identify the points involved and use the formula to compute the average slope.

The cost of 3 pounds of grapes is $6.57. What is the constant of proportionality that relates the cost in dollars, y, to the number of pounds of grapes, x?
Answers
Answer:
$2.19
Step-by-step explanation:
Given that :
Cost of 3 pounds of grape = $6.57
Cost in dollars = y ; number of pounds = x
Cost in dollars α number of pounds
Cost in dollars = k * number of pounds
k = constant of proportionality
$6.57 = k * 3
$6.57 = 3k
Divide both sides by 3
6.57 / 3 = 3k/ 3
2.19 = k
k = $2.19

Answer:
x = 43
Step-by-step explanation:
lines were parallel, then 143 would have to congruent to the vertical angle of 3x + 14
this means that 143 would have to be congruent to 3x + 14
so we can set the equation to 3x + 14 = 143
subtract 14 from both sides: 3x = 129
divide both sides by 3: x = 43
