Answer:

Step-by-step explanation:

y intercept is when x = 0
So, Putting x = 0 in the above function
=> f(0) = 
=> f(0) = 2*1
=> f(0) = 2
So, y-intercept is (0,2)

Answer:
m = -
, c = - 
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Given
2x + 3y + 1 = 0 ( subtract 2x + 1 from both sides )
3y = - 2x - 1 ( divide terms by 3 )
y = -
x -
← in slope- intercept form
with m = -
and c = -
