Answer:

y = - $\frac{3}{2}$ x

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + b ( m is the slope and b the y- intercept )

Calculate m using the slope formula

m = $\frac{y_{2}-y_{1} }{x_{2}-x_{1} }$

with (x₁, y₁ ) = (0, 0) and (x₂, y₂ ) = (2, - 3) ← 2 points on the line

m = $\frac{-3=0}{2-0}$ = - $\frac{3}{2}$

Since the line crosses the y- axis at (0, 0 ) ⇒ b = 0

y = - $\frac{3}{2}$ x ← equation of line

Answer:

1. 8 days

2. $\frac{1}{4}$ pound

3. $\frac{3}{28}$ grams

Step-by-step explanation:

For #1, we have to divide four by $\frac{1}{2}$ (or 0.5), because that's the amount he gives his dog a day. For #2, we have to divide $\frac{1}{2}$ by two, because it is being split into two separate containers (0.5 ÷ 2 = 0.25, or $\frac{1}{4}$ ). #3 is a bit tougher. You can first write it as $\frac{3}{4}$ ÷ $\frac{7}{1}$ (because $\frac{3}{4}$ of gold are being split among seven people), then rewrite this as $\frac{3}{4}$ · $\frac{1}{7}$ . Three times one is three, four times seven is 28. So the final answer is $\frac{3}{28}$ . Hope this helps! Feel free to ask any questions :)
