You could buy 6 keychains spending 4 dollars each. 6 * 4 = $24.
We can use the formula: y = mx + b.
Where m = 2/3 (slope) and (x,y) is (1,1)
Now substitute the values in order to find what "b" is.
1 = (2/3)*1 + b
1 = 2/3 + b
1 - 2/3 = b
1/3 = b
So the equation of the line is: y = (2/3)x + 1/3
To get it into standard form, it should be in the form Ax + By = C
So just multiply the equation by 3 to get rid of the fraction:
3y = 2x + 1
-2x + 3y = 1
Final answer: -2x + 3y = 1
