point slope and slope intercept ​

Answers

Answer:

Step-by-step explanation:

Observe what happens to y if we move from x = 1 to x = 9:  y decreases by 2.  Thus, the slope of the line in question is m = rise / run = -2/8, or -1/4.

Writing the equation in point-slope form, y - k = m(x - h), we get:

y - 7 = (-1/4)(x - 1)      (point-slope form)

Solving for y results in the slope-intercept form:

y = 7 - x/4 + 1, or

y = (-1/4)x + 8     (slope-intercept form)

Divide 2m in the ratio 9-1

Answers

Answer:

Step-by-step explanation:

First, add up the two numbers in the ratio to get 8. Next divide the total amount by 8, i.e. divide £40 by 8 to get £5. £5 is the amount of each 'unit' in the ratio.

To calculate the ratio of an amount we divide the amount by the total number of parts in the ratio and then multiply this answer by the original ratio. We want to work out $20 shared in the ratio of 1:3.
