As we know the formula to calculate the slope is m = y2 - y1 divided by x2 - x1.
Where m is the slope. y2 is the second y co ordinate. y1 is the first y co ordinate. x2 is the second x co ordinate. x1 is the first x co ordinate.
So to calculate we can write it out as -7 = v - (-5) / 5 - 7, which further becomes -14 = v + 5 and v comes out to be -19.
The cost of one package of white chocolate chip cookie is $9 while the cost of one package of oatmeal cookie dough is $14.
<h3>What is an
equation?</h3>
An equation is an expression used to show the relationship between two or more numbers and variables.
Let x represent the cost of white chocolate chip and y represent the cost of oatmeal dough, hence:
12x + 6y = 192 (1)
Also:
6x + 12y = 222 (2)
From both equations:
x = 9, y = 14
The cost of one package of white chocolate chip cookie is $9 while the cost of one package of oatmeal cookie dough is $14.
