Answer (<u>assuming it is allowed to be written in slope-intercept form)</u>:
Step-by-step explanation:
When knowing a line's y-intercept and its slope, you can write its equation using slope-intercept form, or 
.
1) First, find the slope of the line. Read the graph and look at the two points marked on the line - they are (0,1) and (3,-1). Use the slope formula 
, substitute the x and y values of those points, and solve:
Thus, the line's slope is 
.
2) Now, use the slope-intercept formula, , to write an equation. Substitute the 
and 
for real values.
The represents the slope, so substitute in its place. The represents the y-value of the y-intercept, or the point at which the line crosses the y-axis. Looking at the graph, we can see that the line intersects the y-axis at (0,1). Thus, substitute 1 for . This gives the following equation and answer:
Answer:
3.1 hours
Step-by-step explanation:
Average Speed=Distance Traveled ÷ Time Taken
Sherri plans to hike 3.72 miles at an average speed of 1.2 miles per hour.
- Average Speed=1.2 miles per hour.
- Distance =3.72 miles
Therefore:
1.2 miles per hour=3.72 miles ÷ Time
1.2 miles per hour X Time=3.72 miles
Time = 3.72 ÷ 1.2 hours
Time taken by Sherri=3.1 hours
Sherri will hike for 3.1 hours.
ANSWER:
A ) It also increases.
EXPLANATION:
When the measure of angle A increases im the trianes, the measure of angle A on line p also increases. This is angle A in the triangle and angle A on line p are equivalent to each other. Hence, if there is an increase to one of the angle As then there is also an increase to the other.
Therefore, the answer must be:
A ) It also increases.
