On a coordinate plane, a dashed straight line with negative slope goes through (0, 1) and (2, negative 2). Everything to the lef

charle [14.2K]

Answer:

$y$

Step-by-step explanation:

The straight line passes through (0,1) and (2,-2).

Equation of a straight line passing through two points (x1,y1) and (x2,y2)

is given by:

$y-y_{1}=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}(x-x_{1})$

$y-1=\frac{-2-1}{2-0}(x-0)$

$y=-\frac{3}{2}x+1$

Everything to the left of the line is shaded.

We have to visualize the graph:the straight line has a positive y-intercept and a negative slope.The graph is given in the attachment below.

From the figure we can see origin lies on the shaded region.Hence (0,0) should satisfy the inequality.

LHS=y=0

RHS= $-\frac{3x}{2}+1=1\ (x=0)$

LHS<RHS as 0<1

Hence , the inequality is:

$y$

Is using the associative property of addition a good strategy for simplifying (4/3 + 2/3) + 2? Why or why not?

Kitty [74]

Answer:

I say yes because when u solve it and flip the ( )'s, you get the same answer.

Step-by-step explanation:

Work:

(4/3 + 2/3) + 2

6/3 + 2

2 + 2

= 4

4/3 + (2/3 + 2)

4/3 + 8/3

12/3

= 4

Hope this helps!!
