On a school trip the ratio of the number of teachers to number of students is1: 15.the ratio of the number of male students to the number of female students is 7: 5 work out what percentage of all the people on the trip are female students

Step-by-step explanation:

The percentage is 59 percent males 41 percent females

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)
