63. The ratio 63:9 is equal to 21:3 because 3x3 is 9 and 21x3 is 63
Answer:
The new graph has a steeper slope and a y-intercept of 8.
Step-by-step explanation:
From Analytical Geometry, we define a straight line by following first order polynomial (linear function):
(1)
Where:
- Independent variable.
- Dependent variable.
- y-Intercept.
- Slope.
And the slope represents the change in dependent variable (
) divided by the change in independent variable (
). That is:

If
and
, then the new line is steeper with respect to the original line.
Let
, its slope and y-intercept are 5 and 0, respectively. If slope is changed into 9 and y-intercept becomes 8, then the new graph has a steeper slope and a y-intercept of 8.
