Answer:
He will need 8.34 yards of fabric.
Step-by-step explanation:
Given that,
The length of the fabric, l = 2 2/3 yards = 8/3 yards
The width of the fabric, b = 1 1/2 yards = 3/2 yards
We need to find the piece of fabric Roberto needs. It is equal to the perimeter of the fabric such that,
So, he will need 8.34 yards of fabric.
Answer:
y= (2/3)x - 4
Step-by-step explanation:
To answer this you'll want to use the slope intercept form of a line:
y= mx + b
So to solve essentially you just have to find the values for m and b
- m represents the slope of the line
- b is the y-intercept (the point where the line crosses the y-axis)
You can figure that b = -4 because the line will cross the y-axis when x = 0, and you are given the point on the line (0,-4), where x is equal to 0.
Now to find the slope of the line, since you are given two points on the line you will want to use the slope equation:
slope =
So you can assign each of the two points a number (1 or 2) where its values are equal to (x1, y1) or (x2, y2). It does not matter which point gets which number.
In this example:
We will assign the point (6,0) to be (x1, y1),
and we will assign the point (0, -4) to be (x2, y2)
So we end up with the following:
m=
m=
m=
Simplify the fraction:
m =
From there you just substitute in for m and b into the slope intercept equation
