Point slope form is used when we have the information of at least two coordinates that lie on the line
For example:
Given that coordinate (3, 4) and (6, 7) lies on a straight line.
We work out the equation of the line by substituting the two coordinates into the formula (y - y₁) = m(x - x₁) where (x₁, y₁) could be either (3, 4) and (6, 7).
We would need to use both coordinates to work out the gradient (m) by using the formula:
----------------------------------------------------------------------------------------------------------------
The slope intercept form is used when we are given enough information to work out the gradient as well as the y-intercept.
For example:
Given two coordinates (3, 5) and (0, 9)
This information can help to find the gradient and the y-intercept.
The y-intercept would be at 9 because the (0, 9)
We calculate the gradient m
Then substitute into y=mx+c which is the slope intercept form.

Answer:
Cost of one roll of plain wrapping:
Cost of one roll of holiday wrapping paper:
Step-by-step explanation:
Let be "p" the cost in dollars of one roll of plain wrapping paper and "h" the cost in dollars of one roll of holiday wrapping paper.
Based on the information given, we can set up this system of equations:
In order to solve it, we can use the Substitution method. The steps are:
1. Solve for "p" from the first equation:
2. Substitute the above into the second equation and solve for "h":
3. Substitute the value of "h" into :
