What is the equation of the line that passes through the point (4,3) and has an undefined slope?

PLEASE ANSWER
I HAVE TO SUMBIT IN 30 MINUTES:(

x=−4

Step-by-step explanation:

Undefined slope means vertical line. The equation of a vertical line is of the form:

x=   where   is the x coordinate of any point through which you want the line to pass. Therefore, a line with undefined slope that passes through (−4, 3) is:

x=−4

the answer is -6

step-by-step explanation:

the answer is -6 because its next to the variable m

this is a direct variation proportion. y = kx

y is the total amount due, k is the constant of variation, and x is the number of texts sent.

plug in the 3.20 and the 16 to solve for the "k". this is the constant of proportionality. it is the value that will not change.

3.20 = k(16). solving you get $.20 per text.

the equation would then be y = .20x
