PLEASE HELP ITS TIMED I DONT NEED BIG EXPLAINATION WILL DO BRAINLIEST Let i be the imaginary number −1−−−√
. Determine whether the expression a+bi
, where a and b are real numbers, represents a real number or a non-real complex number for each case below. Select Real Number or Non-Real Complex Number for each case.

45

step-by-step explanation:

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)
