Answer:
y=-2x-1
Step-by-step explanation:
First we need to know the slope-intercept equation:
y=mx+b
m: slope
b: y-intercept
First we find the slope:
Slope = (y₂-y₁)/(x₂-x₁)
Use any two x and y values on the table:
Slope = [-5-(-3)]/(2-1) = -2/1 = -2
Now we find the y-intercept:
y=mx+b
y=-2x+b
We plug in a pair of x and y values into the equation:
-3=-2(1)+b
-3=-2+b
b=-1
So the slope-intercept equation is:
y=-2x-1
The tailor can make 8 outfits with 4 4/9 square yards of fabric
<h3>Ratios and proportions</h3>
Given the following parameters;
A baby outfit uses 4/9 square yards of fabric for the hat and 1/9 square yards of fabric for the bib.
- The total fabric used by a baby = 4/9 + 1/9
- The total fabric used by a baby = 5/9 square yards
A tailor has 4 4/9 square yards of fabric, then the total outfit the tailor can make is expressed as:
total outfit = 40/9 ÷ 5/9
total outfit = 40/5
total outfit = 8 outfits
Hence the tailor can make 8 outfits with 4 4/9 square yards of fabric
