Question

find the equation for the slope of a line for -2x+y=-4

Answer 1

rearrange the equation to
the form y = mx + c

m is the required slope

Answer 2

^ where
y=y
m=-2
x=x
-4 = c

Answer 3

do you know how to do thet?

Answer 4

y=-2x+-4

Answer 5

not quite
you add 2x to both sides
so what is the sign of 2x?

Answer 6

Not exactly, using algebra you have to move the -2x to the other side other equation

Answer 7

Srry I kind of confused you

Answer 8

y - 2x + 2x = 2x - 4

Answer 9

y=2x+-4
x=-2

Answer 10

the 2x's on the left disappear to give
y = ?

Answer 11

y=2-4

Answer 12

right y = 2x - 4 is correct
and what is the slope of the line?

Answer 13

-2x

Answer 14

compare
y = mx + c
y = 2x - 4

Answer 15

not - 2x
- the slope is a number

slope = m in the general equation
