Which phrase do we use to indicate that we are trying to study the relationship between two variables while the values of all other variables are held unchanged? A. et ali B. ceteris paribus C. ad hominem D. e pluribus unum Why is this restriction so useful in economic analysis? A. If other variables that do not interact with these two variables are not held fixed, the true relationship between the two variables would be hidden. B. lf every is allowed to change, it would be impossible to isolate the impact of one variable on another.

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)
