1. 3x - 3y = 9
to find the x or y intercept, multiply the other variable that you are not tryng to find by 0
3x - 3(0) = 9 3(0) - 3y = 9
3x = 9 -3y = 9
3x/3 = 9/3 -3y/-3 = 9/-3
x = 3 y = -3
2. I did the same thing for the rest
x = 6 y = -2
3. x = 2.5 y = -5
4. x = -4 y = -2/3
Step-by-step explanation:
105/3 = 35 push ups per minute
35 x 5 = 175 push ups in 5 minutes
N=28
cross multiply 7 and 36
cross multiply 9 and n
7x36=252
9xN=9n
9n=252

Answer:
Mean : 66
Mode: 80
Median:70
Step-by-step explanation:
Mean: sum divided by number of numbers. So, 330 divided by 5 which is 66
Mode most occurring, so 80.
Median arrange in ascending order and find middle value, so 70
Answer:
y = 2x - 3
Step-by-step explanation:
Slope intercept equation of a line:
y = mx + b
(0, -3) is the y-intercept, so b = -3
We have
y = mx - 3
Now we use the two points to find the slope.
slope = m = (-3 - 5)/(0 - 4) = -8/(-4) = 2
y = 2x - 3
