Find the inequality represented by the graph. Can someone please help me!!!!!!

Answer:

y

Step-by-step explanation:

We first need to determine the equation of the line.

Thus, we will need to find our slope first. To do so, we need to pick two points from the line. We can use (0, 5) and (3, 1).

Now, we can use the slope formula. Therefore:

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

Let (0, 5) be (x₁, y₁) and let (3, 1) be (x₂, y₂). Substitute appropriately:

m=\frac{1-5}{3-0}=\frac{-4}{3}

Therefore, our slope is -4/3.

Now, we can use the slope-intercept form:

y=mx+b

Where m is our slope and b is the y-intercept.

We already determined that the slope is -4/3.

And (0, 5) tells us that the y-intercept is 5. Therefore, substitute:

y=-\frac{4}{3}x+5

Finally, we need to determine our inequality sign.

Notice that our line is dotted. Hence, we do not need “or equal to.”

Also, the blue shaded region is below our line. Therefore, y must be less than our equation.

Hence, our sign is less than.

Therefore, our equation is:

y

Solve the system of inequalities to decide if the point (-3,2) is part of the solution; y<=-4x-3, +8y>=7
inna [77]

Answer:

(x,y) = (-3,2) is a solution

Step-by-step explanation:

Given

y \le -4x + 3

x + 8y \ge 7

Required

Determine if (x,y) = (-3,2) is a solution

y \le -4x + 3 becomes

2 \le -4 * -3 + 3

2 \le 15 --- this is true

x + 8y \ge 7

-3+ 8 * 2 \ge 7

13 \ge 7 --- this is also true

Hence,

(x,y) = (-3,2) is a solution
