Determine the slope of the line passing through the points (2,-4) and (15,-9).

Step-by-step explanation:

Use the coordinates given in the slope formula:

Our y2 is -9, y1 is -4, x2 is 15 and x1 is 2

which simplifies to

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)
