Question

Find an equation for the line with the given properties
Parallel to the line 5x-y = -10 containing the points (0,0)

Answer 1

Principle: parallel lines have the same slope.
Action: Find the slope of the given line 5x-y=-10.
I think you mean "containing the point (0,0)," (not points).
Use the point-slope formula of a straight line to determine the desired equation.
You know the slope of this new line and you know that this line passes through (0,0).

Answer 2

apologies for the typo. Is the formula =y -y1 = m(x-x1)

Answer 3

Yes, that's the point-slope formula. The given point is (0,0). What is the slope of the given line? That's the slope y ou'll want to substitute into the point-slope formula to obtain the eq'n of this new line thru (0,0).

Answer 4

will try that again.

Answer 5

Solve 5x-y = -10 for y. Then compare the result to y=mx+b. Identify the value of the slope, m.

Answer 6

i got x=1/5y - 2

Answer 7

hiya mathmale: i got x=1/5y -2

Answer 8

5x-y=10 can be written as y=5x+10

Answer 9

5x - y = -10
when x = 0 y = 10
when y = 0 5x -0 =-10 so x = -2
now you have points on this line find the slope

Answer 10

parallel lines have the same slope so the slope for the "new" line passing through (0, 0) is 5

Answer 11

eqn of line y = mx + b

Answer 12

right.... got it now thank you. Thanks triciaal.

Answer 13

sorry for my (unintended) absence from this discussion.
I was asking you (afievans) to solve the given equation for y (not for x).
5x-y=-10 becomes y=5x+10, which has slope 5.

Answer 14

Then, with slope 5 and point (0,0), the equation of the line thru this point is

y-0=5(x-0), or y = 5x.

Answer 15

I'm curious: How come you solved for x when asked to solve for y? Don't want to put you on the spot, but thought it important to ask you about this.

Answer 16

honestly don't know how i got solving for x. guess i am just overwhelmed. maths is not my best subject...lol

Answer 17

Like anything else, maths gets easier with practice!

Answer 18

i know right.... thanks for helping.
