Answer:
2x + 3y = 20
Step-by-step explanation:
Slope of the line is -2/3 . We can use any of the given points to find the equation of the line. Lets use (1, 6)
The general point-slope form of a line is:
Here m is the slope which is -2/3
x1 and y1 are the coordinates of the point. So x1 = 1 and y1 = 6
Using these values, we get:
1) rearrange one of the formulas so one of the variables is by itself
2) in the other equation replace the variable you solved for with the rearranged equation
3) distribute the 2
4) distrubute the negative
5) combine like terms
6-7) begin to solve for x
8) plug in the value solved for x in the other equation
9-11) solve for y
Final Answers:
x=5/7 y=4
