Answer:
C. In 2001, the temperature was 83°F.
Step-by-step explanation:
79 is 4 less than 83.
The temperature in 2001 was 83 °F.
Answer! :
y = -2x + 5
Step by Step! :
slope intercept form:
y = mx + b
m being slope, b being the y intercept.
To find the slope, use this equation:
y^2 - y^1 / x^2 - x^1
Plug in your points.
(-1) - (7) / (3) - (-1)
-8 / 4
-2 is your slope! (y = -2x + b)
To solve for b, plug in any one of your points and solve for b. Let's use (3, -1)
-1 = -2(3) + b
-1 = -6 + b
5 = b
Your new equation is...
y = -2x + 5
Answer:
7x
Step-by-step explanation:
7x-2(3-4)-2=7x-6+8-2=7x
Answer:
Substitute y with y+10 and x with x-4.
Step-by-step explanation:
To shift every point in the plane 10 down you have to substitute y with y+10 and to shift every point in the plane 4 units right you have to substitute x with x-4.
Suppose the origin of function on the plane is (0,0) now we have to make the origin (4,-10).
first (x,y)=(0,0)
When we substitute x and y
(x-4,y+10)=(0,0)
x-4=0
x=4
y+10 = 0
y= -10
Now the origin is (4,-10).
Hence the function is shifted 10 units down and 4 units right.
