The first thing to recognize that if an equation is in point slope form( y-y1=m(x-x1)) it is a linear equation. Furthermore, because it is in point slope form, the only thing you need to find the equation are the coordinates of two points, which you have: (100, 20) and (300, 25).
First find the m (slope). Do this by completing the formula: (y1-y2)/(x1-x2). In this case, plug in (25-20)/(300-100). When you solve, the answer becomes .025. Then all you need is one of the points to finish the formula.
Thus, the answer becomes y-20=.025(x-100)

Answer:
[tex]y-20=\frac{1}{40}(x-100)[/tex]
Step-by-step explanation:
Slope formula:
100 grams would be an x(1) coordinate
20 cm would be a y(2) coordinate
300 grams would be an x(2) coordinate
20 cm would be a y(2) coordinate
They would be written like this: (100,20), (300,20)
You would use the slope formula to find m
[tex]\frac{y(2) - y(1)}{x(2)-x(1)}[/tex]
Slop-point formula: y-y(1)=m(x-x(1))
When slope is solved, you get 1/40
When solved for slope-point, y - 20 = 1/40 (x-100)
