Answer:
The y-intercept is -15.
Step-by-step explanation:
y - 5 = 5(x - 4) is our equation in point-slope form.
point slope form is = y - y1 = m( x - x1)
So, we know that the slope is 5 and one point is (4, 5)
We can use this point and the slope to find the y -intercept.
y = mx + b is slope intercept form.
Let's input the values we know to find the y-intercept.
5 = 5(4) + b
5 = 20 + b
-15 = b
The y-intercept is -15.
The graph of f(x) = |x| would look like the image below.
Ur answer will be - A≈69.65cm².

The ladder and the outside wall form a right triangle
The length of the ladder is 97.8 feet
<h3>How to determine the
length of the
ladder?</h3>
The given parameters are:
Distance (B) = 22 feet
Angle of elevation (θ) = 77 degrees
The length (L) of the ladder is calculated using the following cosine ratio
cos(θ) = B/L
So, we have:
cos(77) = 22/L
Make L the subject
L = 22/cos(77)
Evaluate the product
L = 97.8
Hence, the length of the ladder is 97.8 feet
