How do you find the slope and y intercept for #y + 4 = 2x#?
2 Answers
Explanation:
We need to transform the equation in the form:
where
slope=
and
Therefore:
graph{2x-4 [-3.862, 6.004, -4.428, 0.506]}
Same thing just, presented a bit differently!
Explanation:
Given:
You could transform this into the standard format of
'~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
The y-intercept is when
So we write the equation as:
But
Subtract
But
'~~~~~~~~~~~~~~~~~~~~~~~~~~~
The slope (gradient) is the number in front of
