Answer:

Step-by-step explanation:
The graph in the attached figure
<em>Find the equation of the dashed line</em>
we have
points (0,2) and (5,3)
<em>Find the slope</em>
The formula to calculate the slope between two points is equal to

substitute the given values


<em>Find the equation of the dashed line in slope intercept form</em>

we have


substitute

Remember that
The solution of the inequality is the shaded area below the dashed line
therefore
The equation of the inequality is

189 inches is 15.75 feet
16 ft - 15.75 ft = 0.25 ft
0.25ft = 3 inches
He must vault 3 inches higher
Answer:

Step-by-step explanation:
We have:

And we want to solve for y when x is -9.
So, substitute -9 for x and evaluate:

Hence, when x is -9, y is -13.
