Complete the equation of the line through (-6, -5) and (-4, -4). Use exact numbers
77julia77 [94]


In general the equation through (a,b) and (c,d) is


(y-b)(c-a)=(x-a)(d-b)


Can you see that this is a line and that both (a,b) and (c,d) are on it?


Here we're given (a,b)=(-6,-5) and (c,d)=(-4,-4)


(y- -5)(-4 - -6) = (x - -6)(-4 - 5)


2(y+5)=x+6


2y + 10 = x + 6


x - 2y  = 4


y = \frac 1 2 x - 2


Either of the last two are fine answers.

Penny solved an equation by subtracting 6 from each side of the equation and then dividing each side by 5.
VikaD [51]

Answer:

Step-by-step explanation:

In order to solve for x, she had to first subtract 6 on both sides of the equation.  Then divide by 5 on both sides of he equation.  After the division part, she was able to successfully isolate x.

The equation she had to solve was     (C)  5x+6=21

First step:  Subtracting 6 on both sides of equation resulted in

5x = 15

Second step:  Dividing both sides of the equation by 5 resulted in

x = 3

Kelvin finished $\frac{2}{3}$ 2 3​​ of his test in a $\frac{1}{2}$ 1 2​​ hour. Express this rate in hours per test.
svet-max [94.6K]

Complete Question

Kelvin finished 2/3​​ of his test in a 1/2​​ hour. Express this rate in hours per test.

Answer:

3/4 hours per test

Step-by-step explanation:

2/3 of his test = 1/2 hour

This rate in hours per test is calculated as:

x = 1/2 /2/3

x = 1/2 hour ÷ 2/3 test

x = 1/2 × 3/2

x = 3/4 hours per test

This rate in hours per test is given as 3/4 hours per test
