Answer:

y=7/5x+7

Step-by-step explanation:

Use the saying "rise over run" to find the slope. If we go from the bottom most dot, we have to rise 7 and run 5 to reach the next dot, making the slope 7/5.

Next, we have to find the y-intercept. Do this by locating where the line crosses the y-axis, in this case it is at 7.

Finally, plug these numbers into slope-intercept format: y=mx+b (m is slope, and b is y-intercept).

Which is an equation in point-slope form of the line that passes through the points (4,5) and (-3,-1)?

Annette [7]

(4,5),(-3,-1)
slope = (-1 - 5) / (-3 - 4) = -6/-7 = 6/7

y - y1 = m(x - x1)
slope(m) = 6/7
using points (-3,-1)...x1 = -3 and y1 = -1
now we sub...pay attention to ur signs
y - (-1) = 6/7(x - (-3) =
y + 1 = 6/7(x + 3) <===

Find the amount accumulated after investing a principle P for T years at an interest rate compounded k times per year.

BartSMP [9]

1. $3500(1+ \frac{.05}{4}) ^{4*10}$
$3500(1+.0125) ^{40}$
3500(1.64) = 5740

2. $25300(1+ \frac{.045}{12} ) ^{12*25}$
$25300(1+.00375) ^{300}$
25300(3.07) = 77671
