Answer: Y = 1/4x - 2
Slope intercept form is y = mx + b
M is slope, and b is y intercept
Solving slope:
change in y over change in x is slope
The change in y from (0,-2) and (4,-1) is up one over four.
This can be represented as 1/4
Solving y-intercept:
Y-intercept is when x = 0 or when the line touches the y axis
As you can see on the graph, the y intercept is (0,-2) or -2
Final:
Y = 1/4x - 2

Answer:
A = -68.75p +2906.25
Step-by-step explanation:
We can solve for m and b using the given values of A and p.
1600 = m·19 +b
2150 = m·11 +b
Subtracting the second equation from the first, we have ...
-550 = 8m
m = -550/8 = -68.75
Substituting this into the first equation gives ...
1600 = 19·(-68.75) +b
b = 1600 +1306.25 = 2906.25
The desired linear equation is ...
A = -68.75p +2906.25

Answer:
Step-by-step explanation:
1) x+27=1
-27 -27
x = -26
2) x-2y=5 (solving for x)
+2y +2y
x = 5 + 2y
2) x-2y=5 (solving for y)
-x -x
2y = 5 -x
2y/2 5/2 -x/2
y = 5 - x
_____
2 (5-x over 2)
