Answer:

Parallel line - y=6x+9

Perpendicular line - y=-1/6x +4

Step-by-step explanation:

Parallel lines have a slope that is equal to the origninal equation. You use the y-y1=m(x-x1) equation. In this case, your y1 is 3 and your x1 is -1. Plug these into the equation along with your slope of 6.

y-y1=m(x-x1)

y-3=6(x-(-1))

y-3=6(x+1)

y-3=6x+6 - Distribute

+3 +3 - Add 3 to both sides

y=6x+9

For perpendicular lines, the slope is the negative reciprocal of the given slope. In this case, the slope is -1/6. Your y1 is 4 and your x1 is 0.

y-y1=m(x-x1)

$y - 4 = - \frac{1}{6} (x - 0)$

Distribute:

$y - 4 = - \frac{1}{6} x$

+4 +4

Add 4 to both sides:

$y = - \frac{1}{6} x + 4$

Hello Tabby We need to solve 4x+2y= 10 for x Let's start by adding -2y to both sides 4x+2y-2y= 10-2y 4x = -2y+10 X= (-2y+10)/4 X= -1/2 y + 5/2 Now substitute -1/2 y +5/2 for x in 3x+2y=6 3( -1/2 y +5/2) +2y = 6 1/2 y + 15/2 = 6 Add -15/2 to both sides 1/2 y +15/2 -15/2 = 6-15/2 1/2 y = -3/2 Y = -3/2/1/2 Y= -3 Now substitute -3 for y in x = -1/2 y +5/2 X= -1/2 y + 5/2 X = -1/2 (-3)+5/2 X = 3/2 + 5/2 X= (3+5)/2 X=8/2 X= 4 Answer x= 4 and y= -3 I hope that's help and please if you have question feel free to ask me :)
