Find the slope and y-intercept of the equation.
The equation of a straight line is :
y = mx + b
m = Slope
b = the Y Intercept
y = - 1 / 3 x - 3
Slope = - 1 / 3
Y Intercept = - 3
how would it be -3 on y intercept?
A y-intercept is a point where the graph of a function or relation intersects with the y-axis of the coordinate system.
As such, these points satisfy x=0
y(x=0) = - ( 1 / 3 ) 0 - 3
y(x=0) = 0 - 3
y(x=0) = - 3
