Answer:

Step-by-step explanation:

use the point slope equation.

y-y1 = m(x-x1)

the point is (x1, y1) = (2, -1)

the slope is m = -3

y+1 = -3( x-2)

y = -3x +6-1

y = -3x +5

A recipe calls for 1 part beans to 1½ parts rice. if 1½ parts of beans are used, how much rice should be used?

riadik2000 [5.3K]

$1 \text{ part beans} \longrightarrow 1\dfrac{1}{2} \text{ parts rice}$

$1 \dfrac{1}{2} \text{ part beans} \longrightarrow 1\dfrac{1}{2} \times 1 \dfrac{1}{2} \text{ parts rice}$

$1 \dfrac{1}{2} \text{ part beans} \longrightarrow \dfrac{3}{2} \times \dfrac{3}{2} \text{ parts rice}$

$1 \dfrac{1}{2} \text{ part beans} \longrightarrow \dfrac{9}{4} \text{ parts rice}$

$1 \dfrac{1}{2} \text{ part beans} \longrightarrow 2\dfrac{1}{4} \text{ parts rice}$
