Answer:

x = 12

y = -3

Step-by-step explanation:

Solving for Y

2x + 7y = 3

x = -4y

2(-4y) + 7y = 3

-8y + 7y = 3

-1y = 3

-1y/-1 = 3/-1

y = -3

Solving for X

x = -4y

x = -4(-3)

x = 12

Checking Work

2(12) + 7(-3) = 3

24 + -21 = 3

3 = 3

x = -4y

x = -4(-3)

x = 12

12 = 12

Find the equation of the line that is perpendicular to y = - 1/3 x + 2 and passes though the point (-5,2)
elena55 [62]

Answer:

y - 2 = 3(x + 5)

Step-by-step explanation:

The given equation has slope -1/3.  Any line perpendicular to the given line has a slope which is the negative reciprocal of -1/3, which comes out to +3.

Use the point-slope formula y - k = m(x - h):

y - 2 = 3(x + 5)
