Slope-intercept form of this equation -1/2x + 8y = -40
GuDViN [60]

Answer:

y = (1/16)x - 5

Explanation:

The slope-intercept form of the equation has the form:

y = mx + b

Where m is the slope and b is the intercept.

So, to write the equation in the slope-intercept form, we need to solve the equation for y:

\begin{gathered} -\frac{1}{2}x+8y=-40 \\ -\frac{1}{2}x+8y+\frac{1}{2}x=-40+\frac{1}{2}x \\ 8y=-40+\frac{1}{2}x \\ \frac{8y}{8}=\frac{-40}{8}+\frac{1}{8}(\frac{1}{2}x) \\ y=-5+\frac{1}{16}x \\ y=\frac{1}{16}x-5 \end{gathered}

Therefore, the slope-intercept form of the equation is:

y = (1/16)x - 5

4. What is the equation of the line?​
Alex73 [517]

Answer:   y= -1/2x + 1  

Step-by-step explanation:

The equation will be represented in slope intercept form because the line is not going through the origin.

Find two points on the line and use them to find the slope since we already know that the y-intercept is 1 because that is where the line intersects the y-axis.

The points  (0,1)  and (2,0)  will be used to find the slope because it is on the line.

The slope will be the difference between the  y coordinates divided by the difference of the x coordinates.  

1- 0 = 1

0 - 3 = -2

Slope:  -1/2  

The equation will be  y= -1/2x + 1
