Write the slope intercept equation of a line that passes through points (-3,4) and (2, -6)
Setler [38]
Find slope by calculating rise over run.
-6-4 / 2-(-3)
-10/5
-2

Then plug one set of coordinates and the slope in to find the b value
-6= -2(2)+b
-6=-4+b
-2=b

Final answer: y=-2x-2

Which expression shows the area of the shaded part of the grid? A hundred grid model showing a 7 4 array shaded blue. A. 0.04 ×
aksik [14]

Answer:

C.\ Area = 0.4 * 0.7

Step-by-step explanation:

See attachment for grid

From the attachment:

There are 10 cells on the horizontal axis and there are also 10 cells on the vertical axis.

This implies that, the measurement of each cell is:

Each\ Cell = \frac{10}{10 * 10}

Each\ Cell = \frac{1}{10}

Each\ Cell = 0.10

The horizontal axis has 7 selected cells.

This measures

Horizontal = 7 * 0.10 = 0.70

The vertical axis has 4 selected cells.

This measures

Vertical = 4 * 0.10 = 0.40

So, the selected area is:

Area = Vertical * Horizontal

Area = 0.40 * 0.70

or

Area = 0.4 * 0.7
