Answer:
B is correct
Step-by-step explanation: an infinite number of solutions means a coincident line...it is the same line
3y = 2x - 9...divide by 3
y = 2/3x - 3...hmm...same line as answer choice b....they are coincident lines and have infinite solutions
Answer:

Step-by-step explanation:
we know that
The linear equation in slope intercept form is equal to

where
m is the slope
b is the y-intercept
<em>Find the slope</em>
The formula to calculate the slope between two points is equal to

take the points
(0,2.5) and (100,97.5)
substitute in the formula



Find the y-intercept b
we have


substitute i the linear equation 

solve for b

Note It was not necessary to calculate the value of b because the value is given in the table
Remember that the y-intercept is the value of y when the value of x is equal to zero (the y-intercept is the point (0,2.5))
The linear equation is

Answer:
Step-by-step explanation:
1x = number of chocolate chip cookies
3x = number of walnut cookies
5x = number of ginger cookies
5x = 40
x = 8
Total cookies = 1x+3x+5x = 72
