You know the slope of a line and a point on the line that is not the y-intercept. Can you use a graph to write the equation of t
Gnoma [55]
Sure you could as long as you have the point.

for example let's say the slope is 2 and the point we are given is (4,4)

we know that:
y = mx + b
plug in the values given
x=4
y=4
m=2

4 = 2(4) + b
b, the y intercept equals -4.

so:

y = 2x - 4
in this case

The admission fee at an amusement park is $1.50 for children and $4 for adults. On a certain day, 378 people entered the park, a
MrRa [10]

Answer:

188 children, 190 adults

Step-by-step explanation:

For this equation, let c be the number of children, and a represent the number of adults.

On this day 378 total people were at the park, so

<em>a + c = 378 </em>   eq 1

Each adult pays $4, so the admission fee for ALL adults will be $4 multiplied by the number of adults , a, so 4a

Use the same method for the children, and the total all children paid is 1.50c

From all the children and adults, the total was 1042, so merge the 2 cost variables together.

<em>4a + 1.50c = 1042 </em>   eq 2

the 2 equations we will use are

a + c = 378

4a + 1.50c = 1042

From equation 1, subtract c from both sides, and

a = 378 - c     eq 3

Substitute the value of a in eq 3 into equation 2

4a + 1.50c = 1042

4 (378 - c) + 1.50c = 1042

1512 - 4c +1.50 c = 1042 (collect like terms)

1512 - 1042 = 4c -1.50 c

470 = 2.5 c

c = 470 /2.5

c = 188 children

Substitute the value of c into eq 3 to get the value of a

a = 378 -c

a = 378 - 188

a = 190 adults
