Write an equation of the line in slope-intercept form given the graph below.
Elza [17]

Answer:

y=-1/3x-1

Step-by-step explanation:

1. Find the slope.

Start from the point on the y-axis and count down and over until you get to the other point marked on the graph. This gets you -1/3

Slope is -1/3

2. Find where the line crosses the y-axis. This is the y-intercept. On this graph, the line crosses the y-axis at (0,-1). The y-value is the intercept.

3. Put the equation in slope-intercept form. Slope intercept form is y=mx+b with mx being the slope and b being the y-intercept.

y=-1/3x-1

Find x if the average of 20, 20, 19, 13, and x is 16
fiasKO [112]
By adding 20+20+19+13+x and dividing by 5 you will receive the answer. Therefore by substituting numbers, 8 will give you the correct average.
20+20+19+13+8 = 80
80/5 = 16.
Therefore x = 8
