Determine the equation of the linear function that has a slope of -4 and passes through the point (2,-4). Write the equation in

padilas [110]

Answer:

Part 1) $y=-4x+4$

Part 2) The graph in the attached figure

Step-by-step explanation:

Part 1)

we know that

The linear equation in slope intercept form is equal to

$y=mx+b$

where

m is the slope

b is the y-intercept

we have

$m=-4\\point\ (2,-4)$

substitute in the linear equation

$-4=-4(2)+b$

solve for b

$-4=-8+b\\b=8-4\\b=4$

substitute

$y=-4x+4$

Part 2) Draw the equation

we know that

To graph a line we need two points

we have the y-intercept (0,4) and (2,-4)

Plot the points, connect them and join to draw the line

see the attached figure

Quadrilateral DXHW∼quadrilateral LSCT

Alex777 [14]

Answer:

HW → CT

∠ X → ∠ S

∠ D → ∠ L

DW → LT

Step-by-step explanation:

The quadrilateral DXHW is similar to quadrilateral LSCT.

So, side HW of the quadrilateral DXHW matches with the CT side of the quadrilateral LSCT.

And angle ∠ X of the quadrilateral DXHW matches with the angle ∠ S of the quadrilateral LSCT.

Again, angle ∠ D of the quadrilateral DXHW matches with the angle ∠ L of the quadrilateral LSCT.

Finally, side DW of the quadrilateral DXHW matches with the LT side of the quadrilateral LSCT. (Answer)
