Sally is going on action with her family. in two hours they travel 90.5 miles. if they travel at the same speed, write an equation that represents how far they will travel, d, in h hours.

m=45.25h

m is miles or the answer and h is how many hours they have driven 45.25 is the miles per hour

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)

answer: 4 (:
