Answer:
y = 1/2x + 4
Step-by-step explanation:
Use the formula for the equation of a line.
y = mx + b
Where m is the slope, and b is the y-intercept.
The slope is given.
y = 1/2x + b
The points (x, y) are given.
(4, 6)
Put y as 6 and x as 4, solve for b.
6 = 1/2(4) + b
6 = 2 + b
6 - 2 = b
4 = b
The y-intercept is 4 or (0, 4).
The equation of the line is y = 1/2x + 4.
Answer:
Ben can type 510 words in 10 minutes.
Step-by-step explanation:
The relation between the number of words typed and the minutes is direcltly proportional, that is, with Ben type more minutes, he will end up typing more words.
Thus, we can use the rule of three:
words | minutes
153 --- 3
x --- 10
Now, we can just cross multiply them:
Thus, Ben can type 510 words in 10 minutes.
