A. slope is rise/run. can count up 3 right 2. slope = 3/2
also by slope formula m = (y - y1)/(x - x1)
B. y-intercept is the y coordinate where the line crosses the y-axis.
See that it is at y = -4 on the graph?
To use the slope.. go backwards from the closest point (4,2) down 2 left 3 gets you to the next point (2,-1) then go down 2 left 3 again to get to y-intercept (0, -4)
C. y = (3/2)x - 4
How you get it is by putting in the values into the standard equation for a line; y = mx + b
m is slope and b is y-intercept.
Answer:
Step-by-step explanation:
These two angles are interior and on the same side of the transversal. Therefore they are supplementary.
6x + x + 5 = 180
7x + 5 = 180 Subtract 5 from both sides
7x = 180 - 5
7x = 175 Divide by 7
x = 175/7
x = 25
x + 5 = 25 + 5 = 30
6x = 6*25 = 150
The minimum number of rows is 1: if A is sorted in descending order, every next students will arrive in a row where everyone is taller than him, and no new rows will be created.
For example, consider
A = [190, 175, 170, 165, 150]
The first students creates the first row.
The second student is 175cm tall. In the first row everyone is taller than him (there's only the 190cm student), so he'll stand in this row.
The third student, 170cm, will find the row filled by the students who are 190 and 175cm tall. So, everyone is taller than him and he'll stand in that row as well.
You keep going with the other students, and you'll see that no one will form a new row.
The sum is 15^2 + 8^2 and it doesn't match any of the above
7×3=21 so he has 7 more lawns or 2 1/3 months
