The line below are parallel. If the green line has a slope of -1/2, what is the slope of the red line?
2 answers:
Answer: B.
Step-by-step explanation:
In the given picture, we have two lines area parallel, one is red and other is green.
We know that the slopes of parallel lines are equal.
Therefore, if the green line has a slope of then ,the slope of red line will also be
because they are parallel.
Hence, B is the correct option.

Answer:
<em>x - 5y = - 10 </em>
Step-by-step explanation:
y = mx + b (b is y-intercept)
m =
~~~~~~~~~~~~
x + 4y = 8 ⇔ y = x + 2 ⇒ y-intercept is 2 and coordinates of y-intercept are <u><em>(0, 2)</em></u>
(5, 3)
m = =
y = x + 2 (slope-intercept form)
<em>x - 5y = - 10</em> (standard form)
