Since the slope is falling, instead of rising, it would be negative.

Now, on the line, I plotted (0, 2) and (-2, 10).

You would now plug this into the rise/run formula.
The formula is $\frac{y2 - y1}{x2 - x1}$

The equation would become,
$\frac{10 - 2}{-2 - 0}$ = $\frac{8}{-2}$ = -4

I believe the answer would be -4.

I hope this helps!

1/7f- 5 1/2= 9/14. what is f?

Alex777 [14]

To solve this equation, we have to isolate the variable f, or get it alone on one side of the equation.

1/7f - 5 1/2 = 9/14

To do this, we need to add 5 1/2 to both sides of the equation to 1) cancel out the - 5 1/2 on the left side of the equation, and 2) maintain equality both sides of the equation.

1/7f - 5 1/2 + 5 1/2 = 9/14 + 5 1/2

1/7f = 6 2/14

Next, we have to divide both sides by 1/7, to get rid of the coefficient of f on the left side of the equation.

1/7f ÷ 1/7 = 6 2/14 ÷ 1/7

f = 43

Therefore, the the value of f is 43.
