Step-by-step explanation:
Given
1 inch = 14 feet
Required
Find the equivalent of 199 feet
Write out the given expression;
1 inch = 14 feet
Divide both sides by 14
Let x represent the equivalent of 199 feet in inches;
Such that:
Substitute
becomes
<em>x = 14.2 inches (Approximated)</em>
The slope formula is:
First, let's solve the slope for Line 1.
a. Subtract y₁ from y₂.
b. Subtract x₁ from x₂.
c. Divide the result in step a by the result in step b.
Hence, the slope of Line 1 is -5.
Let's now solve the slope of Line 2. Use the same steps above.
a. Subtract y₁ from y₂.
b. Subtract x₁ from x₂.
c. Divide the result in step a by the result in step b.
Hence, the slope of Line 2 is 5.
