Step-by-step explanation:
I think it's B i jope that helps but here is some extra info if you like reading(lol)
Earlier in this chapter we have expressed linear equations using the standard form Ax + By = C. Now we're going to show another way of expressing linear equations by using the slope-intercept form y = mx + b.
In the slope-intercept form you use the slope of the line and the y-intercept to express the linear function.
<span><span>y=mx+b</span><span>y=mx+b</span></span>
Where m is the slope and b is the y-intercept.
Example
Graph the equation
<span><span>y−2x=1</span><span>y−2x=1</span></span>
rewrite in slope-intercept form
<span><span>y=2x+1</span><span>y=2x+1</span></span>
Identify the slope and the y-intercept
m = 2 and b = 1
Plot the point corresponding to the y-intercept, (0,1)
The m-value, the slope, tells us that for each step to the right on the x-axis we move 2 steps upwards on the y-axis (since m = 2)
7 x -2 = -14 therefore, d is your answer
Answer:
16.7 miles per hour.
Step-by-step explanation:
1/10 hour is equal to 6 minutes so it takes him 6 minutes to walk 1/6 mile. So he's walked 1 mile in 36 minutes.
Then we divide 1 mile by the time it took him to walk it to know how much distance he walks in 1 minute 1 mile/36=0.277777778
Then you multiply this by 60 because an hour has 60 minutes
0.277777778 x 60=16.7
This means he is walking at 16.7 mph
