Which is the equation of the given line in slope-intercept form? (-1, 2) and (1, -4)

Natalka [10]

1. Find the slope using the slope formula.
$\frac{2 - ( - 4)}{ - 1 - 1} = \frac{2 + 4}{ - 2} = - \frac{6}{2} = - \frac{3}{1} = - 3$
2. Plug that slope and either point into an equation in slope-intercept form and solve for b.
$2 = - 3( - 1) + b \\ 2 = 3 + b \\ - 1 = b$
3. Now write your answer as a slope-intercept form equation
$y = - 3x - 1$

9. A movie theater sells small and large pretzels. A small pretzel costs $2. A large pretzel costs $4.50. A total of 50

seraphim [82]

Answer:

30 small pretzels were sold that night.

Step-by-step explanation:

x = small pretzels

y = large pretzels

x + y = 50

2x + 4.5y = 150

x + y - y = 50 - y

x = 50 - y

2(50 - y) + 4.5y = 150

100 - 2y + 4.5y = 150

2.5y = 50

------- -----

2.5 2.5

y = 20

x + 20 = 50

x + 20 - 20 = 50 - 20

x = 30
