Write the equation of the lines in slope-intercept form (y=mx+b)
First equation: It is already in slope-intercept form
Second equation: solve y:
Identify the slope of each line:
If two or more lines have the same slope then the lines are parallel
If two lines have slopes that are negative reciprocals then the lines are perpendicular
The two given lines have the same slope: 2/5. Then, they are parallel lines
Answer:
I'm taking the test right now so i'll tell you the right answer after I submit my test but for now I think it's C.
Step-by-step explanation:
step 1. the standard form of a quadratic equation is f(x) = ax^2 + bx + c
step 2. since they are all in standard form you need to provide more information.
That bracket symbol, with an r in it, means "the absolute value of r".
So r's absolute value is -2 meaning r is two units from zero
r= 2
