Q: Math Help Please Again

Directions: find three ordered pairs that solve the equation and draw the graph of each of the following.
10) question: y=3x - 5
0, -5, and 2,0, and 4,5.
2
question: 5x - 3y = 15
5x - 3y = 15
5(6) - 3y = 15
30 - 3y = 15
-3y = -15
y = 5 therefore, (6,5) is the answer
you are correct that (6,5) is a solution, but you need at least two points to draw a line graph. Try using x = 0 and see what you get for y. Again, I also need to see the graph.
50) question: x = 5
0,5 2,5 4,5
the line goes straight over.
Section 4.2 #50.
You graphed the equation y = 5 instead. Your graph shows points like (-2, 5), (0, 5), and (2, 5), where the y value is always 5.
Since x = 5 is fixed by the equation, we can and need use any points with x = 5:
(5, 0), (5, 1), (5, 2) are good examples. This line should be straight up and down (vertical), crossing the x-axis at 5.
