Which of these points lies on the line described by the equation below y-3=5(x-9)
2 answers:
Answer:
(9,3)
Step-by-step explanation:
We have been given an equation of a line and we are asked to find the point that lies on our given line.
Since we know that point-slope form equation of a line is: , where,
m = The slope of the line.
= The coordinates of given point on the line.
Since our given equation is in point-slope form, so x-coordinate of our given point is 9 and y-coordinate of our given point is 3.
Therefore, point (9,3) lies on the line described by our given equation.

Answer:
Step-by-step explanation:
Setting it up as a fraction will help us see the simplification process a bit easier.
a/a = 1, so they cancel each other out, leaving us with simply
If you graph the end points C and D then graph the 4 points at the end it is difficult to tell which points are on CD without a line.
Using the endpoints find the slope (change in y/ change in x) then substitute a point in to find the intercept.
Slope = (-6-4)/(6- -8) = -5/7
Intercept equation (-6) = -5/7 (6) + b
b = -1.71428571429
Graphing the line shows only 2 points on the line (–2.75, 0.25) and <span>(0.75, –2.25)
I am confused by the part, "</span><span>P is the length of the line segment from D". Were you given a length P to help you determine which point. Using the distance formula to find the length from each point to D doesn't help determine which one is best with the information you have given. The image shows the distances I calculated and the graphed points.
