8. Write the equation of a line that is perpendicular to the given line and that passes through the

1 answer:

8 0

Y - 3 = 8/3(x + 2)...the slope here is 8/3. A perpendicular line will have a negative reciprocal slope. All that means is " flip " the slope and change the sign. So our perpendicular line will have a slope of -3/8

y - y1 = m(x - x1)
slope(m) = -3/8
(-2,3)....x1 = -2 and y1 = 3
now we sub
y - 3 = - 3/8(x - (-2)...not done yet
y - 3 = -3/8(x + 2) <===

Y = 3x + 15 3x + 3y = 9

Zina [86]

Answer:

$\Large\boxed{x=-3}$ $\Large\boxed{y=6}$

Step-by-step explanation:

Given the system of equations

$1)~y=3x+15$

$2)~3x+3y=9$

Divide 3 on both sides of the 2) equation

$3x+3y=9$

$3x\div3+3y\div3=9\div3$

$x+y=3$

Current system

$1)~y=3x+15$

$2)~x+y=3$

Substitute 1) equation into the 2) equation

$x+(3x+15)=3$

Combine like terms

$x+3x+15=3$

$4x+15=3$

Subtract 15 on both sides

$4x+15-15=3-15$

$4x=-12$

Divide 4 on both sides

$4x\div4=-12\div4$

$\Large\boxed{x=-3}$

Substitute the x value into one of the equations to find the y value

$y=3x+15$

$y=3(-3)+15$

$y=-9+15$

$\Large\boxed{y=6}$

Hope this helps!! :)

it's from Khan Academy and there are answer choices it's called interpet negative number addition and subtraction expression

kolbaska11 [484]

Answer: Hi!

Answers B and D are correct.

For B, since negative numbers are on the left side of the number line, a positive number would have to be to the right of a negative number. Since we are adding a negative and a positive number of the same absolute value (9), they would cancel out to 0, which makes D true.

Hope this helps!
