What is the equation for a line that passes through the points (-5,-4) and (10,14)?

Answers

Answer 1

Answer:

Answer:

y=6/5x+2

Step-by-step explanation:

1.find the slope(m)

m=y2-y1/x2-x1

m=14-(-4)/10-(-5)

m=14+4/10+5

m=18/15

m=6/5

y-y1=m(x-x1)

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

y+4=6/5(x+5)

y+4=6/5x+30/5

y=6/5x+30/5-4

y=6/5x+10/5

y=6/5x+2

Write down a number you can square to give an answer bigger than 400 but smaller than 500

Answers

If you would like to know a number you can square and the answer is bigger than 400 but smaller than 500, you can calculate this using the following step:

20^2 = 400 < 21^2 = 441 < 22^2 = 484 < 500

There are two correct results: 21 and 22.

What is 4 over 10 in simplest form

Answers

ok so find 1's

remember that 4/4=1 also x/x=1 those are ones
also remember
if you had
10/30 that equals 10/10 times 1/3=1 times 1/3

so find ones

4/10=2/2 times 2/5=1 times 2/5=2/5

2/5 is 4/10 reduced to simplest form
