To find y = mx + b you need to determine the slope. To find slope use the formula
m = y2 - y1 / x2 - x1

Use two points on the graph such as (4, 100) and (12, 300)

Now plug it into the formula

m = 300 - 100 / 12 - 4

m = 200 / 8

m = 25

Now we know the slope, but we need to find the y-intercept.

y = mx + b

y = 25x + b

Substitute one of the points (4, 100) as the y value and x value to find b, the y intercept

100 = 25(4) + b

100 = 100+ b

100 - 100 = b

0 = b

Now plug in your formula

Y = 25x + 0

y = 25x

Lance says that you can compare any decimal numbers the way that you alphatbetize words you can tell which number is first by co
Afina-wow [57]

Answer:

No, Lance's thinking is wrong because you cannot compare decimal numbers with alphabetizing words. For example, if we compare 37.6 to 7.42 using the method of Lance, we would probably say 37.6 is less than 7.42 because 3 is less than 7. But it is wrong. The 3 in 37.6 is in the tens place. On the other hand, 7.42 contains no tense. Therefore, 37.6 is actually higher.
