1) We are given points on the line of the graph (0,3) and (1,1).
Rise/run represents the slope of the line.
Rise/run = -2/1 = -2.
Therefore, slope of the line is -2.
<h3>Correct option is A) -2 .</h3>2) Given equation y=7.5x-5.
From the graph we can see that line crosses x-axis at 0.667.
But we don't find any such option.
But we can see line crossing y-axis is -5.
It seems that we need to find the point where line cut y-axis.
<h3>Therefore, correct option is C option.</h3><h3>C) - 5</h3>
Answer:
Number of 2-point shots taken = 12
Number of 3-point shots taken = 6
Step-by-step explanation:
Total number of points scored by Gladys = 42
Only 2-point and 3-point shots are taken by Gladys.
Let number of 2-point shots taken =
Let number of 3-point shots taken =
Total number of shots taken = 18
Therefore, first equation can be written as:
Total points scored = 42
Therefore, second equation can be written as:
System of equations is:
Using elimination method to solve the system of equations.
Multiplying equation by 2 then subtracting it from equation (2):
By equation (1):
Therefore, Number of 2-point shots taken = 12
Number of 3-point shots taken = 6
