The maximum is 4 days
200:42= 4,76
You should buy 106.25 ft 2, because if you multiply 8.5 times 12.5 you would get that answer, which is the area of the wall.
Answer:
y=x-3 (assuming your graph is counting by ones)
Step-by-step explanation:
Slope is 1, I chose two points.
0,-3 and 4,1
Then found the slope with those two points, which was 1.
Then I find the y-intercept, which is where the line and point crosses the y axis, which was -3.
So, I made my equation.
9514 1404 393
Answer:
- slope: 6; y-intercept: -3
- slope: 11; y-intercept: -1
- slope: 2; y-intercept: -13
- slope: 1; y-intercept: -6
Step-by-step explanation:
The slope is found using the slope formula. It works well to choose ordered pairs that only differ by 1 in their x-value.
m = (y2 -y1)/(x2 -x1)
The y-intercept is the y-value when x=0. If it is not in the table, it can be found from one point and the slope.
b = y1 -m·x1
__
1) slope = (9 -3)/(2 -1) = 6
y-intercept = -9 -6(-1) = -3
__
2) slope = (21 -(-1))/(2 -0) = 22/2 = 11
y-intercept = -1 . . . from table for x=0
__
3) slope = (-9-(-11))/(2-1) = 2
y-intercept = -11 -(2)(1) = -13
__
4) slope = (-4 -(-5))/(2 -1) = 1
y-intercept = -7 -1(-1) = -6
