What is the y intercept of y = 3x - 4?

In y = mx + b form, the y intercept can be found in the b position

y = mx +  b
y = 3x + (-4)

so ur y intercept is -4

Ifound this on google “that means that the graph of a function with direct variation has these features: it is a straight line: because the slope is the ratio y/x = k. it passes through the origin (0,0): because y = kx = k (0) = 0.” i hope this you for what your looking for
