Answer: No
Find the equation of the line using slope-intercept form: y = mx + b
y = -1/2x + b ^ ^
slope y-intercept
Find b, the y-intercept (where the line intersects the y-axis) by substituting the coordinates of point Q (6, 7).
y = -1/2x + b Subtitution
7 = -1/2(6) + b Simplify
7 = -3 + b Add 3 to both sides
10 = b Isolated b
b = 10 Isolated b
Using the above information, find the equation of the line.
y = -1/2x + b
y = -1/2x + 10
To find if point S (2,5) lies on the line, substitute in its coordinates in the equation of the line.
y = -1/2x + 10 Substitution
5 = -1/2(2) + 10 Simplify
5 = -1 + 10 Simplify
5 = 9 --> If the statement is true, the point lies on the line.
If the statement is false, the point does not lie on the line.
In this case, 5 does not equal 9. Therefore, point S does not lie on the line.

Answer:
3
Step-by-step explanation:
To find the slope of the line, you can use the formula rise/run.
Every time the graph moves one unit across the x-axis, it moves three spaces up. Therefore,
Rise = 3
Run = 1
Now to plug this into our formula:
3/1 = 3
The slope of the line is 3.
Find the slope of A. The slope of a line parallel to A would have the same slope of A. Remember, slope=rise over run.
