Question

Write an inequality to represent the graph.

Answer 1

Answer:

$y \leq -\frac{3}{4}x+2$

y is less than or equal to negative three fourths times x plus 2

Step-by-step explanation:

step 1

Find the equation of the solid line

we have the coordinates (0,2) and (4,-1)

Find the slope m

The formula to calculate the slope between two points is equal to

$m=\frac{y2-y1}{x2-x1}$

substitute

$m=\frac{-1-2}{4-0}$

$m=\frac{-3}{4}$

$m=-\frac{3}{4}$

Find the equation of the line in slope intercept form

$y=mx=b$

where

m is the slope

b is the y-intercept (value of y when the value of x is equal to zero)

we have

$m=-\frac{3}{4}$

$b=2$ ---> is given

substitute

$y=-\frac{3}{4}x+2$

Remember that

The shading area is below the line

therefore

The inequality is

$y \leq -\frac{3}{4}x+2$

y is less than or equal to negative three fourths times x plus 2
