Video Solution

Solution Steps

00:00 Find the algebraic representation of the function
00:03 Isolate Y
00:13 This is the equation of the parallel function
00:16 This is the slope of the parallel function
00:19 Parallel functions have equal slopes
00:22 We'll use the line equation
00:28 We'll substitute the point according to the given data
00:37 We'll substitute the slope and solve to find the intersection point (B)
00:50 Isolate the intersection point (B)
00:59 This is the intersection point with the Y-axis
01:07 Now we'll substitute the intersection point and slope in the line equation
01:18 And this is the solution to the question

Step-by-Step Solution

First, write out the line equations:

4+y=5x6 -4+y=5x-6

y=5x+46 y=5x+4-6

y=5x2 y=5x-2

From here we can determine the slope:

m=5 m=5

We'll use the formula:

y=mx+b y=mx+b

We'll use the point (2,13) (-2,-13) :

13=5×2+b -13=5\times-2+b

13=10+b -13=-10+b

3=b -3=b

Finally, substitute our data back into the formula:

y=5x+(3) y=5x+(-3)

y=5x3 y=5x-3

Answer

y=5x3 y=5x-3
