Answer 1

it's multiple choice take what are your answers?

Answer 2

1. parallel lines have the same slope (x).
2. y - y1 = m(x - x1) is point slope form, to use it simply plug in the x and y values of a coordinate into x1 and y1

Answer 3

3. (5, 8)
what is the x value?
4. (4, -6)
what is the y value?
atleast show some effort :P

Answer 4

im terrible at math

Answer 5

practice and you'll get better. us showing you the answer will only set you up for failure when the test comes around.

Answer 6

what do you have trouble with?

Answer 7

this kind of stuff

Answer 8

ok, let's start with #1
Write the slope-intercept form of the equation parallel to y = 7x + 2, which passes through the point (1, -3).

Answer 9

first: what is slope intercept form?

Answer 10

y=mx+b?

Answer 11

yep and in y = mx + b. m = slope and b is a number.

Answer 12

lines are parallel if they have the same slope.
in english: if the value for m is equal in two equations, then they have the same slope and are parallel.

Answer 13

one more thing to address:
have you heard of point slope form?

Answer 14

ya

Answer 15

great, in a problem like this you'll need to use point slope form which is:
y - y1 = m(x - x1)
x1 = x coordinate
y1 = y coordinate
m = slope

Answer 16

go back to what you were given:
y = 7x + 2 and coordinates (1, -3). plug them into point slope form.
in the equation "y = 7x + 2" you only need the slope.

Answer 17

still confused? i'll write it out

Answer 18

ya just a little
