Two points (4,1) and (4,2) lie on a vertical line. Find the slope of the line that passes through both points. (5 points) m= 0 or no slope undefined slope m=1/2 m = 1

the slope of a vertical line is undefined

Step-by-step explanation:

its undefined because it doesn't move horizontally. however if you had a horizontal line, the slope would be 0

= 5

step-by-step explanation:

to find the 15th term substitute n = 15 into the nth term formula

= (- 3 × 15 ) + 50 = - 45 + 50 = 5
