Answer:

I will solve your system by substitution.

y=2;2x+y=8

Step: Solvey=2for y:

Step: Substitute2foryin2x+y=8:

2x+y=8

2x+2=8

2x+2+−2=8+−2(Add -2 to both sides)

2x=6

(Divide both sides by 2)

x=3

Answer:

x=3 and y=2

Write a equation of a line perpendicular to the line below in point-slope from that passes through the point (-2,6)

STatiana [176]

Answer:

Option 1: $y-6=-4(x+2)$

Step-by-step explanation:

Find the slope of the perpendicular line by finding the negative reciprocal of the original slope. (Negative reciprocal = flip upside down and add a negative). So we get -4 for the perpendicular slope.

Next, we know the point (-2,6) is on the line, so we can get x=-2 and y=6.

Plug this into point-slope form: $y_{1}-y_{2}=m(x_{1}=x_{2})$

$y_{1} - (6)=-4(x_{1}-(-2))$

$y-6=-4(x+2)$

$(3x) \times 3 - 2 = 1$

$(3x \times 3) - 2 = 1$

$9x - 2 = 1$

Add sides 2

$9x - 2 + 2 = 1 + 2$

Simplification

$9x = 3$

Divide sides by 9

$\frac{9x}{9} = \frac{3}{9} \\$

$\frac{9}{9} x = \frac{3}{9} \\$

$x = \frac{3}{3 \times 3} \\$

$x = \frac{1}{3} \\$
