I need help. Why is Algebra 2 so hard ;--;

second and fifth

Step-by-step explanation:

The equation of a line in point- slope form is

y - b = m(x - a)

where m is the slope and (a, b) a point on the line

Calculate m using the slope formula

m =

with (x₁, y₁ ) = (- 3, 4) and (x₂, y₂ ) = (- 2, - 1) ← 2 points on the line

m = = - 5

Using (a, b) = (- 2, - 1 ), then

y - (- 1) = - 5(x - (- 2) ) , that is

y + 1 = - 5(x + 2) ← subtract 1 from both sides

y = - 5(x + 2) - 1  ← second option

Using (a, b) = (- 3, 4) , then

y - 4 = - 5(x - (- 3) ) , that is

y - 4 = - 5(x + 3) ← add 4 to both sides

y = - 5(x + 3) + 4 ← fifth option

the ratio of white tiles to blue tiles is 48: 16. the ratio in it's simplest form is 3: 1.

step-by-step explanation:

ratio: take the first number and add a colon next to it, then add the second number after that. make sure the ratio order matches up with the written problem!

simplest form: we can simplify the ratio 48 : 16 by dividing both terms by the greatest common factor (gcf).

the gcf of 48 and 16 is 16.

divide both terms by 16:

48 ÷ 16 = 3

16 ÷ 16 = 1

reducing to simplest form:

48 : 16 = 3 : 1
