Find the slope of the graph of the linear equation. 2x+y=7

  1. Slope is 2    
  2. Slope is 7    
  3. Slope is -2    
  4. Slope is –7    

hintHint:

compare given straight line equation with intercept form of equation
y = mx + c

The correct answer is: Slope is 2


    -2 is the correct choice
    given equation:
    2 x plus y equals 7
y space equals space minus 2 x space plus space 7 space...... left parenthesis a right parenthesis
w e space k n o w space t h e space i n t e r c e p t space f o r m space o f space e q u a t i o n space
space y space equals space m x space plus space c space....... left parenthesis b right parenthesis
h e r e space m space equals space s l o p e
c o m p a i r space e q u a t i o n space left parenthesis a right parenthesis space a n d space space left parenthesis b right parenthesis
a n d space space w e space g e t comma space space m equals negative 2
s o space s l o p e space o f space t h e space l i n e space 2 x plus y equals 7 space space equals space minus 2
