How do you write the equation of a line (in slope intercept form) with three given points?​
Mrrafil [7]

With even just two points, you can find the equation of a line in slope-intercept form.

Slope-intercept form: y=mx+b where m is the slope and b is the y-intercept

<u>1) Solve for the slope (</u>m<u>)</u>

The equation to solve for the slope is m=\frac{y_2-y_1}{x_2-x_1} when the two points are (x_1,y_1) and (x_2,y_2). Plug the coordinates of these points into the equation and solve for m.

Then, plug m into y=mx+b.

<u>1) Solve for the y-intercept (</u>b<u>)</u>

Then, take any of the given points and plug it into y=mx+b along with the slope. Isolate b to get the y-intercept. Then, plug both m and b back into y=mx+b to get your final equation.

I hope this helps!

Robin can clean 72 rooms in 6 days how many can he clean in 9 days
Monica [59]
Let's put it this way. 
It's a ratio of 6:72 and we need to change it in a way to find number of rooms cleaned in 9 days.

Divide 6 & 72 both by 2
Ratio is now 3:36

Multiply 3 & 36 both by 3
Ratio is now 9:108

The number of rooms in which Robin can clean in 9 days is 108 rooms.
