The formula is y = mx + b when b = y-intercept and m is the slope.
Slope = Rise/Run So 1/2.
Y-Int. = The y value at which x = 0. Which is -3
The line has the formula:
Y = 1/2x - 3
Hope this helps :)
Hello from MrBillDoesMath!
Answer:

Discussion:
Angle J = 180 - (120 + 40) = 180 - 160 = 20 degrees,
From the law of sines
sin(120)/k = sin(20)/2 =>
sin(120) = k * ( sin(20)/2) ) (multiply both sides by "k")
k = sin(120)/ ( sin(20)/2) (divide both sides by sin(20)/2)
k = (0.866) / ( 0.171) = 5.06

Answer:
We have a total of 7200 plants.
The plants are distributed in one field with 18 rows of 200 plants and another field with 9 rows of N plants.
Where we want to find the value of N.
The total number of plants in the rows is:
"number of rows times number of plants in each row."
Then the total number of plants is:
18*200 + 9*N
And we know that we have a total of 7200 plants, then:
18*200 + 9*N = 7200
9*N = 7200 - 18*200 = 3600
N = 3600/9 = 400
Then the plants are distributed in 18 rows of 200 plants for one field, and 9 rows of 400 plants in the other field.
