Answer:
y = 1/3x -1
Step-by-step explanation:
We have 2 points (9,2) and (42,13)
We can find the slope
m = (y2-y1)/(x2-x1)
= (13-2)/(42-9)
=11/33
=1/3
The slope is 1/3
We can use the point slope form of the equation
y-y1 = m(x-x1)
y-2 = 1/3(x-9)
Distribute
y-2 = 1/3x -3
Add 2 to each side
y-2+2 = 1/3 x-3+2
y = 1/3x -1
It depends on the technology you want to use.
These days, most programs that produce images have a way to set the zoom factor. Changing that changes the scale of the drawing.
When copy machines are used for reducing or enlarging, the scale factor is set to something new by selecting the appropriate enlargement or reduction.
If you're drawing a graph, you change the scale by changing the number of units a grid line represents.
54/8 = 6 6/8 . . . . . the 1st selection is appropriate
Answer:
I think it is B because it represents the amount of trail mix and the no. of pound bought is increase
Step-by-step explanation:
first plot a xy on the graph and make a number in the graph like 2468 and Mark 2.50 in the graph and the question says that it is buying meor and income will also be more and draw a line as answers of B
W+d=869
w=d-81
plug in
(d-81)+d=869
2d-81=869
+81 both sides
2d=950
÷2 both sides
d=475
dryer cost $475
let's check w=475-81
w=394
475+394=869
869=869
the solution is true :)
