Answer:
undefined
Step-by-step explanation:
To find the slope of the line between two points, use the slope formula 
. 
and 
represent the x and y values of one point the line passes through, and 
and 
represent the x and y values of another point the line also passes through. Therefore, use the x and y values of the points (0,3) and (0,4) to find the slope. Substitute them into the formula in the right order:
However, we can't divide 1 by 0. Therefore, the slope is undefined. (You could also graph the points to see that they form a vertical line, and all vertical lines have an undefined slope.)
The number of variables in the problem is 3
Answer:
x = 
Step-by-step explanation:
The altitude of the triangle must equal 4 because it is a right triangle with another leg of 3 and a hypotenuse of 5 (reason is due to the pythagorean theorem)
Therefore, the triangle on the right has legs of 4 and 7 and, again, use the phythagorean theorem to find 'x' (the hypotenuse)
+ 
= 
16 + 49 =
65 =
x = sq rt 65
Answer:
Step-by-step explanation:
Flip the equation.
Add -9 to both sides
Divide both sides by 7/8
