Answer:

Step-by-step explanation:

y = \frac{-1}{5}x - 4\\\\Plugin x = 0  , y = 0 - 4\\\\   y = -4\\\\(0 ,  -4)\\\\Plugin x = 5, y =\frac{-1}{5}*5-4 = -1-4=-5\\\\(5 , -5)\\\\Plugin x = -5, y =\frac{-1}{ 5}*(-5)-4=1 - 4 = -3\\(-5, -3)

Plot the points(0 ,-4) , (5 , -5) and (-5 , -3 ) in the graph and join the points.

Fran has a poster that measures 3/4 square yard in area the length of the poster is 1/3 yard what is the width of the poster
Harrizon [31]

Answer:

9/4 yards

Step-by-step explanation:

A poster is a rectangle.

Area of rectangle = Length × Width

Given:

Area = 3/4 yd

Length = 1/3 yd

Substitute the given values to the equation.

3/4 = 1/3 × w

3/4 = 1/3w

3/4 ÷ 1/3 = w

3/4 × 3/1 = w

9/4 = w
