The graph for the coordinate points (0, 5), (1, 5.5), (2, 6), (3, 6.5) and (4, 7) is plotted below.
The general equation of a straight line is y=mx+c, where m is the gradient, and y = c is the value where the line cuts the y-axis. This number c is called the intercept on the y-axis.
The given equation of a line is y=1/2x+5.
Substitute x=0, 1, 2, 3, 4, 5,....in a equation y=1/2x+5, we get
When x=0, y=5
When x=1, y=5.5
When x=2, y=6
When x=3, y=6.5
When x=4, y=7
So, the coordinate points are (0, 5), (1, 5.5), (2, 6), (3, 6.5) and (4, 7)
Therefore, the graph for the coordinate points (0, 5), (1, 5.5), (2, 6), (3, 6.5) and (4, 7) is plotted below.

Answer:
Step-by-step explanation:
Y/1 = 2x + 5
Y = 2x + 5
Y = 2x + 5
When x = 1
Y = 2 ×1 +5
Y = 2 + 5
Y = 7
When x =0
Y = 2 × 0 + 5
Y = 5
When x = -2
X = 2 × -2 + 5
X = 1

Answer:
I belive it's $703.13
Step-by-step explanation:
She worked for 40 hrs which will give her, her normal pay. You do 450/40 to get 11.25. So her normal pay is $11.25. Then it says she earns 1.5 times the normal amount, so you would do 11.25 * 1.5. That equals 16.875. so her pay for every hour after 40. 55-40=15. That means she will have 15 hours where she gets 1.5 times her normal pay. So you do 16.875 * 15=253.125. She gets $253.125 for her extra 15 hours of work. Next, you need to add the total amount earned for the 40 hours. 450+253.125=703.125. Her total for the week she worked 55 hours she earns $703.13.
I hope this makes sence and helps. ( * means multiply)
The answer is 43 and the way the solve it is do the division first and then add 2
the 2nd problem is 9 and that one is pretty straightforward
First add 2 to both sides to cancel:
x/3 = 5
then multiply by 3 to both sides to cancel the 3:
x=15
Answer: 15, x=15
Step-by-step explanation: Start off by adding 2 to both sides. So then you have x/3 = 5.
Then multiply each side by 3 so you get 15.
X=15
