Line IJ has an equation of a line y = 3x − 8, and line KL has an equation of a line y = 3x + 4. These two lines are

parallel because the slopes of the lines are the same

perpendicular because the product of the slopes is −1

both representations of the same line

neither parallel nor perpendicular

jim_thompson5910 · Answer

What is the slope of y = 3x − 8?

What is the slope of y = 3x + 4?

anonymous · Answer

idk how to find the slope

jim_thompson5910 · Answer

y = mx+b is your general form

m is the slope

jim_thompson5910 · Answer

example

y = 7x+10
y = mx+b

so m = 7 is the slope

anonymous · Answer

ok @jim_thompson5910

jim_thompson5910 · Answer

So what is the slope of each?

anonymous · Answer

7 @jim_thompson5910

jim_thompson5910 · Answer

That's the slope of y = 7x+10

jim_thompson5910 · Answer

The number in front of the x is the slope

but that's NOT the slope of y = 3x - 8

jim_thompson5910 · Answer

What's the slope of y = 3x - 8?

@jim_thompson5910  sorry my computer is running slow and 
13

jim_thompson5910 · Answer

where are you getting 13?

jim_thompson5910 · Answer

are you adding two numbers?

anonymous · Answer

i multiplied 3 by 7 got 21 and subtracted 8

jim_thompson5910 · Answer

the slope is simply the number in front of the x
