The point-slope form of a line that has a slope of –2 and passes through point (5, –2) is shown below.
Ilya [14]

Answer:

y =-2x+8

Step-by-step explanation:

We have a point and a slope

(5,-2)  and m =-2

The slope intercept form of a line is

y = mx+b

y = -2x+b

Substitute in the point

-2 = -2(5)+b

-2 = -10+b

Add 10 to each side

-2+ 10 = -10+10 +b

8 = b

The equation is

y =-2x+8

HeLp would be appreciated for the image below :))
erik [133]

Answer:

A

Step-by-step explanation:

The line from the vertex to the base is a perpendicular bisector and divides the isosceles triangle into 2 right triangles.

Using Pythagoras' identity in either of the 2 right triangles, then

(\frac{1}{2} x )² + 3² = (\sqrt{45} )²

\frac{1}{4} x² + 9 = 45 ( subtract 9 from both sides )

\frac{1}{4} x² = 36 ( multiply both sides by 4 to clear the fraction )

x² = 144 ( take the square root of both sides )

x = \sqrt{144} = 12 → A
