Answer:

\text{The equation of line with slope 2 and passing through the point (5, 6) is }y=2x-4

Step-by-step explanation:

Given the equation of line QR is

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

we have to find the equation of a line perpendicular to line QR in slope-intercept form that contains point (5, 6).

The slope-intercept form is

y=mx+c

Compare general equation with given equation.

m=-\frac{1}{2}

As we know the slope of perpendicular line of negative reciprocal of given line therefore, the slope of perpendicular to line QR is

m=2

The equation of line with slope m and passing through the point (x',y') is

y-y'=m(x-x')

Therefore, the equation of line with slope 2 and passing through the point (5, 6) is

y-6=2(x-5)

y-6=2x-10

y=2x-10+6

y=2x-4

which is required slope-intercept form of line perpendicular to line QR.

Any perpendicular line has a negative reciprocal slope. So your slope would be 2. The. You would have the equation : y=2x+b. You would then replace the coordinate (5,6) with x and y on your line to solve for b. Your equation would be : y=2x-4

Which fractions are greater than -5/16 ?
AlladinOne [14]
-5/16 

Our choices:-

A.-3/8
 
 
 B.-11/12
 
 
 C.-1/4
 
 
<span> D.-1/8
</span>
Let us get all of them with a LCD

-1*2 = -2
8*2 = 16

-2/16 is not bigger than -5/16

-11/12 is bigger than -5/16 because half of 16 is 8.

-1*4 = -4
4*4= 16

-4/16 is not bigger than -5/16

-1/8 is smaller than -5/16

Final answer: -11/12 is the only fraction bigger than -5/16
