what does the number become when it is say -4/0?

Question

the question is:
what is the equation of a line that passes through the points (7,3) and (7, -3) ? its multiple choice and the answer choices are
A. x= 3 B. x= 7 C. y= -3

Answer 1

-4/0 is indeterminate

2.slope=1/0
so the line is parallel to y axis
x=7 is the equation

Answer 2

The answer is B. x=7. If you plot the points on a graph it would be a vertical line through the point (7,0). Therefore, the equation of the line would be x=7. You also asked "what does the number become when it is say -4/0?" I'm assuming that -4/0 is the slope of the line. Since no number is divisible by zero, the slope of the line is undefined which would be a vertical line crossing through the x-axis.

Answer 3

Looks like you were trying to calculate the slope which is -6/0.

Anyway, for the first part-- the answer is UNDEFINED. Any number, be it negative, positive, fraction, or decimal when divided by zero is undefined. An undefined slope means the line is Vertical.

The second part-- the answer is B. Equation of line is a straight line perpendicular or vertical to the x axis at x=7. To see it more clearly, plot the points: one in the first quadrant and the other in the fourth quadrant. Connect the points and the line is a vertical that passes through x=7.

Answer 4

the answer is (B. x=7)

know why?

if you have 2 points, with the x passing through 7 on them both, that means it is a straight up and down line. it doesn't matter what the y is. if both the y's were 7, it would be y=7.

Answer 5

dividing by zero in your slope calculation means that the line is vertical through the points. so the equation is just x=7

Answer 6

slope is undefined. (meaning the line is vertical) the equation is x=7 because both the x values are sevens. (you may have made it too hard)

Answer 7

In (x,y), x is constant, so:

x = 7
