Which line has a slope of frac{1}{3} and goes through (3, -1)?
1 answer:
Answer:
y=1/3x - 2
Step-by-step explanation:
The question asks for the equation of a line with a slope of 1/3 and passes through point (3,-1)
The equation for the line in the slope intercept form is written as y=mx+c where m is the gradient and c is the y-intercept
But you know m=Δy/Δx where Δx =x-3 and Δy=y--1
cross-multiply
Divide every term by 3
The line is

Answer:
The parents' club can afford to buy 100 Baseball hats or 100 sports bottles.
Step-by-step explanation:
Given:
Item to be bought = 100
Total Budget = $250
Cost of each Baseball Hat = $2.45
Cost of each sports bottles = $2.50
Cost of each flag = $2.75
We need to find which items can they afford to buy.
Solution:
each Baseball Hat = $2.45
100 Baseball Hat = Cost of 100 Baseball Hat
Using Unitary method we get;
Cost of 100 Baseball Hat =
each sports bottles = $2.50
100 sports bottles = Cost of 100 sports bottles
Using Unitary method we get;
Cost of 100 sports bottles =
each flag = $2.75
100 flags = Cost of 100 flags
Using Unitary method we get;
Cost of 100 flags =
Hence from above we can see that;
Cost of 100 Base ball hat and 100 sports bottles are within the budget while Cost of 100 flags exceed the budget.
So we can say that;
The parents' club can afford to buy 100 Baseball hats or 100 sports bottles.
