Answer:
slope = 1
y-intercept = (0 , -4)
x - intercept = (4 , 0)
Step-by-step explanation:
y = mx + b
m = slope
b = y-intercept
Note that there is no number besides the x. When this happens, the slope is to be assumed as 1.
The number (and sign) that replaces the b is the y-intercept. In this case, it is (0 , -4).
The x-intercept is the point in which you intercept the y-line at 0. Plug in 0 for y, and solve for x:
0 = 1(x) - 4
0 = x - 4
0 (+4) = x - 4 (+4)
x = 4
x-intercept = (4 , 0)
5y+45=180
5y=135
y=135/5
y=27
Answer
y-1=5(x-2)
Step-by-step explanation:
1-(-4) =5
2-1=1
y/x = 5/1 =5
(2,1)
y-1=5(x-2)
5 feet = 60 inches
4 1/2 inches = 1 hour
60 inches = 1 ÷ 4 1/2 x 60
= 13 1/3 hours
If the snow keeps accumulating, it would take 13 1/3 hours for 5 feet of snow to accumulate.
(-3).
We plug (-1) for x in g(x) and we get:
(-1) - 2(-1)^2.
To simplify, (-1)^2 turns to just 1. since a negative times a negative gives a positive.
Then, we have (-1) - 2(1) or (-1) - 2 or -1 - 2.
This is then -3
