2. A line goes through the points (4, 5) and (2, -6). Write the equation of the line in slope-intercept form. Show your work for

full credit. (How did you go from those two points to having the equation in slope-intercept form? Or, how did you go form having the equation in point-slope form [above in #1] to slope- intercept form?). Do not draw graphs, I want you to complete this problem algebraically (Using numbers, variables, and/or symbols). Circle your answer. (4 points)

Answer:

y = 5.5x - 17

Step-by-step explanation:

(4,5)(2,-6)

  • M = ∆y/∆x
  • -6-5/2-4
  • -11/-2 this is the gradient
  • chose any of the point then introduce another point
  • (4,5) (x,y) the gradient is -11/-2
  • M =∆y/∆x
  • y-5/x-4 = -11/-2
  • -2(y-5) = -11 ( x -4)
  • -2Y + 10 = -11x + 44
  • -2Y = -11x + 44 -10
  • -2Y = -11x + 34
  • divide the while equation by -2
  • y = 5.5x + - 17
  • y= 5.5x - 17

Two angles are complementary. If the measure of one angle is twice the measure of the other angle, what is the measure of the la
Alenkinab [10]
Two angles are complementary: x + y = 90 (complementary = 90 degrees)
x = 2y

plug in 2y for x

2y + y = 90
3y = 90
3y/3 = 90/3
y = 30

plug in 30 for y
x = 2y
x = 2(30)
x = 60

x (the largest angle) = 60°

To model this situation, we are going to use the exponential function: f(t)=P(1+ \frac{r}{n} )^{nt}
where
P is the initial number of cars
r is the growing rate in decimal form 
n is number of tames the growing rate is increasing per year
t is the time in years

To convert the growing rate to decimal form, we are going to divide the rate by 100%
r= \frac{12}{100}
r=0.12
Since the growing rate is increasing quarterly, n=4. We also know that the initial number of cars is 920, so P=920. Lets replace all those values in our function:
f(t)=920(1+ \frac{0.12}{4} )^{4t}
f(t)=920(1+0.03)^{4t}
f(t)=900(1.03)^{4t}

We can conclude that:
Rate ---------> The quarterly rate of growth is 0.03 or 3%
Exponent --------> The compound periods multiplied by the number of years                                 is 4t
Coefficient--------> The initial number of cars serviced is 920
Base------> The growth factor is represented by 1.03
