A. What is the slope of the given line?
B. What is the slope of the line perpendicular to the given line?
C. What is the slope of the line that is parallel to the given line?
D. Find the equation of the line that is perpendicular to the given line and passes through the point (-1, 2).
E. What is the y-intercept of the equation from part (D)?
F. Find the equation of the line that is parallel to the given line and passes through the point (0, -6).
G. What is the x-intercept of the equation from part (F)?

Answer 1

First of all, what does "slope" mean in this context, and how does one find a "slope" when given two points on a line?

Answer 2

Slope is the run over rise . It is that how much a line moves on x axis ( that is run ) as compared with the y axis

Answer 3

thank you, @Imad_Sawal, but my question was meant for @mw647.

Answer 4

@mathmale the formula is slope = y2 - y1/x2 - x1 correct?

Answer 5

Yes (although I'd suggest that you please use parentheses for clarity).\[m=(y _{2}-y _{1})/(x _{2}-x _{1}) \] Identify any two points on the graph and substitute the appropriate x- and y-coordinates into the slope formula.

Answer 6

@mathmale So would the slope be \[\frac{ -9 }{ -7}\]

Answer 7

Hi !
First find 2 point .
I Got :
A=(2,0)
B=(4,-6)
Then use :
m=y2-y1/x2-x1
we have :
y2=-6
y1=0
X1=2
X2=4
m=-6-0/4-2=-6/2=-3
@mw647 : Got it ?:)

Answer 8

@E.ali Awesome thank you!
