Question

Find the slope-intercept equation of the line that passes through the point (-2, 4) and is parallel to
y = -3x + 6.

Answer 1

Please help me!

Answer 2

ok... when they tell u PARALLEL means that both line have the same slope

Answer 3

the slopes of parallel lines are equal.

Answer 4

yes

Answer 5

so, in the eq. that they r giving u y=-3x+6

Answer 6

can u identify the slope?

Answer 7

-3?

Answer 8

perfect

Answer 9

so there is a formula to find the slope intercep..
y-y1=m(x-x1)

Answer 10

y-4=-3(x-(-2))

Answer 11

and that is like the one we just did

Answer 12

okay, so it's y=3x+10, then what?

Answer 13

y-4=-3(x+2)
y-4=-3x-6
y=-3x-2

Answer 14

chek ur signs

Answer 15

oh, opps... I forgot the -...

Answer 16

cool

Answer 17

okay, thanks!

Answer 18

from second equation we know that slope is -3
Point/Slope Form of an Equation
A line going through the point (x1,y1) and
having slope of m would have the equation y-y1 = m (x - x1)
This gives
y-4=-3[x-(-2)]
y-4 = -3[x + 2]
y - 4 = -3x -6
y = -3x -6 + 4
y = -3x - 2

Answer 19

thanks what we got,, thanks for the summary
