Find an equation of the line perpendicular to the graph of 14x-7=1 that passes through the point at (-2,4)
wolverine [178]

we know that

If two lines are perpendicular, then the product o their slopes is equal to minus one

so

m1*m2=-1

Step 1

<u>Find the slope of the given line</u>

we have

14x-7=1\\14x=1+7

x=8/14 -------> x=4/7

This line is parallel to the y-axis

so

the perpendicular will be parallel to the x-axis

Step 2

The equation of the line perpendicular to the given line is the y-coordinate of the given point

Point (-2,4)

the equation is

y=4

therefore

<u>the answer is</u>

y=4

see the attached figure to better understand the problem

Someone pls help asap this is due tmrw !!<br><br> x - 3y = -12<br> 2x + 3y = 3
hram777 [196]

Answer:

Step-by-step explanation:

to solve this system of equations we will add them

x-3y=-12

2x+3y=3 now +3y-3y=0

3x=-12+3

3x=-9

x=-3

plug in the first equation

-3-3y=-12

-3y=-12+3

-3y=-9

y=3
