Which is an equation of the line that passes through the points (-6,-8) and (4,-4)
natita [175]

Answer:

y=\frac{2}{5}x-6.5

Step-by-step explanation:

\frac{(-8)-(-4)}{(-6)-4} \\ = \frac{-4}{-10} = \frac{2}{5\\}

y=mx+b

-8 = (\frac{2}{5}) (-6) +b

-8 = - \frac{12}{8} +b

13 - r &lt; 82<br><br><br><br><br> PLA I NEED THIS
maria [59]

Answer:

r > -69

Step-by-step explanation:

13 - r < 82

subtract 13 from both sides

13 - r - 13 < 82 - 13

- r < 69

to flip the inequality sign, multiply both side by -1 to make r positive:

- r (-1) < 69 (-1)

r > -69
