Answer:

Option D is correct

The point slope intercept equation of line = y-9=2(x-1)

Step-by-step explanation:

Given: The slope of line (m) = 2 and also it is given from the figure the

Point-slope intercept form: If we have a point (x_1, y_1)  and a slope, m, then the formula

we  use to find the equation of a line:

y-y_1=m(x-x_1)  .......[1]

Substitute the value of m =2 and (1, 9)  in [1];

y-9=2(x-1)

Therefore, the point slope intercept equation of the line is: y-9=2(x-1)

Answer:

Option: D is the correct answer.

The equation of line in point-slope form is given by:

y-9=2(x-1)

Step-by-step explanation:

We know that the point-slope equation of a line is given by:

y-b=m(x-a)

where (a,b) is the point from which the line passes and m is the slope of the line.

Here we are given that:

The line passes through (1,9) and slope of the line is given to be 2.

Hence,

(a,b)=(1,9) and m=2

Hence, the equation of line is given by:

y-9=2(x-1)

Seth invested n dollars into an investment fund last year. After a period of one year, the value of his investment can be repres
Crank

Answer: A. The value of his investment decreased by 16% during this time period.

Step-by-step explanation:

Here the initial amount = n

Final amount after 1 years = 0.84n

The total change in the initial amount = n - 0.84n = 0.16 n

\text{ The percentage change in the initial amount} = \frac{\text{ the total change in initial amount}}{\text{ Initial amount}}\times 100

= \frac{0.16 n }{n} \times 100 = 16\%

Thus, the amount is decreases by 16% in one year,

⇒ Option A is correct.

What line has slope of 5/8 and goes through the point (2,-3)
sweet-ann [11.9K]
Slope of a line passing through a point is given by: y - y1 = m(x - x1); where (x1, y1) = (2, -3) and m = 5/8.
Therefore equation of the line is y - (-3) = 5/8(x - 2)
8(y + 3) = 5x - 10
8y + 24 = 5x - 10
8y - 5x = -10 - 24 = -34
5x - 8y = 34
