Dovator [93]

Answer:

C

Step-by-step explanation:

The equation of a line is given by y-y_1=m(x-x_1)

and

slope (m) is given by:

m=\frac{y_2-y_1}{x_2-x_1}

Where (x_1,y_1) are the first set of point in the line and (x_2,y_2) is the second set of point

<em>Let's take 2 points arbitrarily. (0,0) & (25,20)</em>

<em />

<em>Let's plug it and find the equation:</em>

<em>m=\frac{20-0}{25-0}=0.8</em>

<em>Now</em>

<em>y-y_1=m(x-x_1)\\y-0=0.8(x-0)\\y=0.8x</em>

<em />

<em>C is the correct answer.</em>

Bria ordered 145 centimeters of fabric. Jayleen ordered 1.5 meters of fabric. Who ordered more fabric?
lubasha [3.4K]
Bria: 145 centimeters
Jayleen: 1.5 meters

I'm going to convert Jayleen's into centimeters:
1 meter has 100 centimeters

1.5 x 100 = 150 centimeters

so,
Bria:145 centimeters
Jayleen: 150 centimeters

So, Jayleen bought more fabric
