In a table, like the one below, the domain is usually listed in the left column and the range is listed in the right column. You can also refer to the domain as the input values, x, and the range as the output values, y, in a relation or function.
Answer:
y = 5x - 9
Step-by-step explanation:
y - y₁ = m(x - x₁), where (x₁, y₁) = (3, 6)
y - 6 = 5(x - 3)
y = 5x - 15 + 6
y = 5x - 9
If the markers are 4.5 inches away on the map, and 2.5 inches represents 10 miles, then we need to make ratios we can work with.
Inches / Miles:
4.5 / x
2.5 / 10
Now, we can cross multiply to end up with:
2.5 * x = 4.5 * 10
Simplify:
2.5x = 45
Divide 2.5 on each side:
2.5x / 2.5 = 45 / 2.5
Simplify:
x = 45 / 2.5
x = 18
Awesome! Now we have a real ratio on the real distance of the markers.

18 miles is the actual distance between the two markers.
Hope I could help! If my math is wrong, or it isn't the answer you are looking for, please let me know!

Answer:
Both D and E are true statements.
Step-by-step explanation:
When you have the base form of slope-intercept form:
y = mx + b
The m (which is the coefficient of x) is the slope of the line. In this case that would be 4.
The b is the intercept. In this case it would be -6
