What is the slope and y-intercept for the line represented by this equation? 5x+13y= -13

Question

saifoo.khan · Answer

For slope, make "y" the subject and then the value for "x" is the slope.

[PS 
y = mx + b is the equation for slope]

anonymous · Answer

The slope is given by the coefficient in front of x (the number in front of x) when the equation is in standard form y=mx+b. So solve for y and see what you get :-)

5x+13y= -13 

13y = -13  - 5x
DIvide 13 from both sides,
$$ y = \frac{-5x - 13}{13}$$$$y = -\frac{-5}{13}x - \frac{13}{13}$$Now compare it with 
y = mx +b

therefore, slope = -5/13

:-/ spoiled the suspense for sergeantpepper (btw sergeantpepper "solve for y" means get your equation to be y= "something").

anonymous · Answer

is the y-intercept -13 or -1?

anonymous · Answer

the y-intercept is b in the equation y=mx+b (note that when x=0 we have y=b so that's when we go through the y-axis-when x=0, hence the name the y-intercept).

anonymous · Answer

so the y-intercept is -13?

anonymous · Answer

it is -13/13=1
