To find this, you have to find your slope with the given x and y values first. Use the equation Y2-Y1/X2-X1 for finding the slope.
4-1/3- -6
3/9= 1/3
Now you know your slope is 1/3, and you can basically assume your third answer listed is correct since none of the other ones contain a positive 1/3 but I will explain how to continue for future use. Next you can use one set of x and y values to plug into the equation y=mx+b, and plug in 1/3 for m as well.
4=1/3(3) + b
4 = 1 + b
-1 -1
3 = b
Now you have your y intercept and your slope, so you can make your equation.
Y= 1/3x + 3

Developing spirit of hard work means to understand the definition and beliefs of hard work, as it teaches us discipline, dedication, and determination. Ways to motivate yourself to work harder is to breakup your tasks into smaller tasks so you can see where your obstacles are, and you can be prepared to overcome them. Also by staying focused, positive, and reminding yourself why you are doing the work in the first place.
Hope that helps :)
Let the three numbers be x, y and z. Then x+y+z=75.
z = 2x. y = x - 9.
Eliminate y and z by substitution: x + (x - 9) + (2x) = 75
Then 4x = 75 + 9, or 4x = 84. x = 21, y = 21 - 9 = 12, and z = 2(21) = 42.
Check: Do 21, 12 and 42 add up to 75?
