The admission fee at an amusement park is 1.5 dollars for children and 4 dollars for adults. On a certain day, 321 people entered the park, and the admission fees collected totaled 844 dollars. How many children
and how many adults were admitted?

x=-2

infinite number of lines, so there is an infinite number of equations.

step-by-step explanation:

there are an infinite number of line that passes through the point (-2,5)

x=-2   is one line that passes through the point

y = 5 is another line that passes through the point

(these two lines are perpendicular to each other).

since the number of   numbers are infinite and the slope is the ratio of two numbers,(change in y over change in x) we can have an infinite number of slopes.     our only condition is that it passes through the point (-2,5)

b. 153 students do not participate in sports and seventy-five 12th graders were surveyed

there still no table
