1.You should draw a line of best fit for a scatter plot if there is no correlation among the data points.

True
False

2.You have to spend on x candles and y batteries for your hurricane supplies. Candles cost .00 each and a pack of C batteries cost .50 each. Write an equation in standard form to represent your purchase of these supplies.

6.5y = 3x 25

y = 6.5 over 3 x 25

3x 6.5 y = 25

6.5y 25 = 3x

3.Which of the following equations represents y =-7 over -2 - x 3 in Standard form?

7x 2y = 3

7x 2y = 6

7x 3y = 6

x 7 over 2 y = 3

4. What is the x-intercept and the y-intercept of the graph of 6x - 3y = 18? pleas show the work

5.Write an equation of a line with slope m = -2/ 5 and passing through the point (5, -2).

y = -2/5 x - 2

y = -2/5 x

y = -2/5 x 2

y = -2/5 x 4

it might look like alot of work but its only 4 questions and all they want to no is if you use a bar graph, a line graph, a scatter plot, or a pie chart for the information. please help im not good with this kind of stuff.

2. You have to spend on x candles and y batteries for your hurricane supplies. Candles cost .00 each and a pack of C batteries cost .50 each. Write an equation in standard form to represent your purchase of these supplies.

A. 6.5y = 3x + 25
B. y = x + 25
C. 3x + 6.5 y = 25
D. 6.5y + 25 = 3x
