<h2>Answer:</h2>
<em>(Check the attached image).</em>
<h2>Step-by-step explanation:</h2><h3>1. Identify the given information.</h3>a. We have the slope of the line, 1/4.
b. We also have a point of said line, because when the question states "y-intercept 5..." it's telling us that the lines touches the y intercept on the value y= 5, and this only happens when x= 0. Hence, a given point is (0, 5).
• Formula for constructing linear equations.
Formula: ; where m is the slope of the function; x1 is the x value of a point the function passes through, and y1 is the y value of a point the function passes through.

Answer: Sue spends travelling 3.5 hours and spends stationary 2.5 hours
Step-by-step explanation:
The attached image shows Sue's distance-time graph, from there we can observe the segments where she is stationary (lines with no slope) and the segments where she is travelling (lines with slope).
<u>Time spent travelling:</u>
From 2 p.m. to 3 p.m. is 1 hour
From 3:30 p.m. to 4 p.m. is 0.5 hour
From 5 p.m. to 6:30 p.m. is 1.5 hours
From 7:30 p.m. to 8 p.m. is 0.5 hour
Total time travelling=1 h+0.5 h+1.5h+0.5h=3.5 h
<u>Time spent stationary:</u>
From 3 p.m. to 3:30 p.m. is 0.5 hour
From 4 p.m. to 5 p.m. is 1 hour
From 6:30 p.m. to 7:30 p.m. is 1 hour
Total time travelling=0.5 h+1 h+1h=2.5 h
Answer:
The x-coordinate of the x-intercept that is located to the left of the origin is equal to -1
Step-by-step explanation:
we have the function
we know that
The x-intercepts are the values of x when the value of the function is equal to zero
using a graphing tool
The function has three x-intercepts
The x-intercepts are the points
(-1,0),(1.5,0) and (2,5,0)
see the attached figure
The x-intercept that is located to the left of the origin is the point (-1,0)
therefore
The x-coordinate of the x-intercept that is located to the left of the origin is equal to -1
