Answer:

y < \frac{1}{2}x-3

Step-by-step explanation:

We will find the equation of the dotted line first.

Let the equation of the line is,

y = mx + b

Here, m = slope and b = y-intercept of the line

Slope 'm' = \frac{\text{Rise}}{\text{Run}}

m = \frac{3}{6}

m = \frac{1}{2}

Y-intercept 'b' = -3

Therefore, equation of the line is,

y = \frac{1}{2}x-3

Since, this line is a dotted line, it will represent an inequality with notation of less than or greater than (< or >)

Since, solution area (shaded area) of this inequality is below the line inequality will be,

y < \frac{1}{2}x-3

Answer:

s = 10w

Step-by-step explanation:

We can find the equation in <u>slope-intercept form</u> which is y = mx + b. The variables mean:

"b" - for the y-intercept (where the graph hits the y-axis)

"m" - for the slope (how steep the line is)

"x" and "y" - coordinates that satisfy the equation (points on the line)

From the graph, we can see that the y-intercept is 0. b = 0, therefore we do not need to write it in the equation.

To find the slope, "m", use the equation  m = \frac{y_{2}-y_{1}}{x_{2}-x_{1}}. To use it, substitute the coordinates for two points. Using the diagram, choose a point 1 and a point 2.

Point 1 (0, 0)      x₁ = 0   y₁ = 0

Point 2 (1, 10)     x₂ = 1   y₂ = 10

m = \frac{y_{2}-y_{1}}{x_{2}-x_{1}}          Substitute values

m = \frac{10-0}{1-0}          Subtract to simplify

m = \frac{10}{1}          Simplify the fraction

m = 10            Slope of the line

Since we know "m" and "b", we can write the equation:

y = mx + b

y = 10x + 0

y = 10x

We are not using "x" and "y" in this case. Change them according to the question.

x => w

y => s

y = 10x   =>   s = 10w

Y=-25x+325 What is the slope of this equation?
Bezzdna [24]

Answer:

-25

Step-by-step explanation:

This equation is in the form y = mx + b where m is the slope and b is the y-intercept. Knowing this, we see that -25 is in place of m, so that's our answer.
