Answer:

Step-by-step explanation:
we know the slope (or m in y=mx+b) is 6/5 we just need to solve for b
we will do this by plugging in the required coordinates
-2=(6/5)*5+b
-2=6+b
-8=b
put it all together
Answer:
b= 9.17 ft
Step-by-step explanation:
The 4 feet from the wall is the bottom part of the triangle. The 10 ft. ladder is the hypotenuse of the triangle. Use the Pythagorean Theorem and substitute the known values.
a^2+b^2=c^2
4^2+b^2=10^2
Then square all the known values
16+b^2=100
Then get b by itself
b^2=-16+100
add -16 and 100
b^2=84
and finally square root both sides of the equation
b=9.16515 ft or 9.17 ft
