acxbox22 · Answer

first find the equation of both equations

sparklestaraa · Answer

Function B- f(x)=3
Function A- 2+5*x

sparklestaraa · Answer

@confluxepic @Directrix

directrix · Answer

Put the y with the equation for A:  y = 5x + 2

The second equation is not correct.

directrix · Answer

Pick two points from the chart for Line B. Place them in this online calculator and crank out the equation. Post what you get. http://www.mathportal.org/calculators/analytic-geometry/two-point-form-calculator.php

sparklestaraa · Answer

3x-y+5=0
y=3x+5 @Directrix

directrix · Answer

A: y = 5x + 2

B: y=3x+5

Yes, that is what I got for B.

Now look at the two equations. 

Do they have the SAME slope?  @Sparklestaraa

directrix · Answer

Recall the general form:

y = m*x + b  where m is the slope and b is the y-intercept. @Sparklestaraa

sparklestaraa · Answer

they have the same slope i think am i right? @DanJS

directrix · Answer

No.

A: y = 5x + 2

 B: y=3x+5

Look at these. Line A has slope 5 and Line B has slope 3. They are not the same.

directrix · Answer

Now, what about the intercepts?

sparklestaraa · Answer

Ohhh i thought it was 5/3 and 3/5 xD

directrix · Answer

Nope.  In y = mx + b form, just look at the coefficient of x.

directrix · Answer

Let's finish this and move on:  Now, what about the intercepts?    @Sparklestaraa

sparklestaraa · Answer

the intercepts are different? @Directrix

directrix · Answer

That is correct.

So, what is the answer to the question?

sparklestaraa · Answer

A- y=7x?
B- y=8x?

directrix · Answer

Look at the question you posted. There is no option that looks like that.

directrix · Answer

Look at these. Which one describes the two lines we have looked at?

Their slopes are equal, but y-intercepts are not equal
.Their slopes are not equal, but y-intercepts are equal.
 Both slopes and y-intercepts are equal.
 Neither slopes nor y-intercepts are equal.

directrix · Answer

Look at what you wrote in this thread:  the intercepts are different? @Directrix

directrix · Answer

Look at what I wrote:

. Line A has slope 5 and Line B has slope 3. They are not the same.

Put those together and select the answer.

ohhhh D ?

directrix · Answer

At long last, that is correct.
