<span>Answer: two options apply: A and D.
</span>
<span /><span /><span>A. As the y-intercept increases, the graph of the line shifts up.
D. As the y-intercept decreases, the graph of the line shifts down.
</span><span />
<span>Justification:
</span><span>1) Take the slope-intercept equation of the line: y = f(x) = mx + b</span>
<span /><span>
</span><span>2) The y-intercept is b
</span>
<span /><span /><span>
3) When b is increased, f(x) will increases too, that is f(x) will be higher or its graph will be shifted up, which is what the option A. states.
</span><span />
<span>4) When b is decreased, f(x) will decreases too, that is f(x) will be lower or its graph will be shifted dOwn, which is what the option D states.
</span><span />
<span>5) Regarding the options B and E, which deal with motions in the horizontal direction (left or righT), nothing can be said, as the effect of a change in the y -intercept on the horizontal direction will depend on the slope.
</span><span />
<span>6) Regarding the option C, a change in the y-intercept does not change the slope (the steep of the line).

Answer:
Danielle earns more in 1 hours and $0.80 more than MacKenzie
Step-by-step explanation:
Given : Danielle earns $36.80 for 4 hours of yardwork. MacKenzie earns $50.40 for 6 hours of yardwork.
To find : Who earns more money per hour? How much more
Solution : We have given
Danielle earns in 4 hours = $36.80 .
Danielle earns in 1 hours = .
Danielle earns in 1 hours = $9.20 .
MacKenzie earns in 6 hours = $50.40
MacKenzie earns in 1 hours = .
MacKenzie earns in 1 hours = $8.40.
We can see Danielle earns more in 1 hours .
How much = $9.20 - $8.40.
= $0.80.
Therefore, Danielle earns more in 1 hours and $0.80 more than MacKenzie
