Question 5(Multiple Choice Worth 4 points)
Trava [24]

Answer: it is -1

Step-by-step explanation: rate of change can be defined as Δy/Δx, or the change in y over the change in c (commonly referred to as rise over run). By looking at the numbers we can see that the relationship modeled is linear (has a constant rate of change), so we are able to use this formula to calculate its rate of change. Simply calculate the change between any two values of y and (the associated) values of x and divide them to obtain your solution. I’m not the best at explaining math in words so here is the solution represented symbolically:

Rate of change = Δy/Δx

Δy/Δx = (y2-y1)/(x2-x1)

(y2-y1)/(x2-x1) = (1 - (-2))/(2 - 5) //the selected values for y2,y1,x2, and x1 are the last and first values for each, respectively.

3/-3 = -1

How do i put this in slope-intercept form. passes through 2,-2 and 4,-1​
enot [183]

Answer:

\large\boxed{y=\dfrac{1}{2}x-3}

Step-by-step explanation:

The slope-intercept form of an equation of a line:

y=mx+b

<em>m</em><em> - slope</em>

<em>b</em><em> - y-intercept</em>

The formula of a slope:

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

We have two points (2, -2) and (4, -1).

Substitute:

m=\dfrac{-1-(-2)}{4-2}=\dfrac{-1+2}{2}=\dfrac{1}{2}

Put the value of a slope and the coordinates of the point (2, -2) to the equation of a line:

-2=\dfrac{1}{2}(2)+b

-2=1+b              <em>subtract 1 from both sides</em>

-3=b\to b=-3

Finally:

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