4) According to the table, is the exam grade a function of the number of hours spent studying? A) Yes, it is a function because no one failed the test.
B) Yes, it is a function because the student who studied more hours made the best grade.
Yes, it is a function because the exam grade increases by 2 points for each houn studied.
Dy No, it is not a function because the input value of hours has 2 different output values of 78 and 821

i dont know but hope u do

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)

none cuz there are no "following statements" regarding the question

step-by-step explanation:

step-by-step explanation:

step 1: solve one of the equations for one of the variables. let's solve the first equation for y:

step 2: substitute that equation into the other equation, and solve for x.

step 3: substitute x = 4 x = 4 x=4 into one of the original equations, and solve for y.
