The equation of a line is shown below: y = - x - 7 What is the equation of a line which is parallel to this line and passes through (1, 79)? y = -x + 80 y = x - 80 y = 7x - 80 y = -7x + 80
@sleepyjess
Parallel means that they must have the same slope. What is the slope of the given equation and the answer choices?
is the asner c or d
Do you know how to get the slope?
no
Slope-intercept form of an equation is y = mx + b, m is the slope. So what is the slope of the given equation?
y = -x-7?
what is the coefficient before x? Hint: if there isn't a coefficient, it is either 1 or -1 depending on the sign.
7?
-x, is there a coefficient?
no
Ok, now is the sign negative or positive?
negative
Ok, so the slope of the given equation is -1
ok
is the answer c o. d
You will see.
For the first option, what is the slope? Remember all we need to look at is the coefficient before x.
