Answer 1

use point slope formula
\[\frac{ y2-y1 }{x2-x1 }\]
is slope is undefined (you divide by 0) then its a vertical line at your given x value

Answer 2

y2 - y1 / x2 - y1 = m

-2/0

Answer 5

use the slope formula.. y2-y1/ x2- x1

Answer 6

where 4 is your x1, 5 is y1..4 is x2 and 3 is y2

Answer 7

substitute then viola, you'll have the slope
