Consider a graph of the equation y = - 3x + 4. What is the y-intercept?

Y = - 3x + 4

In y = mx + b form, the y intercept will be in the b position.

y = mx + b

y = - 3x + 4 ... so ur y intercept is 4 ... or (0,4)

just so u know ... in y = mx + b form, the slope will be in the m position ... so ur slope would be - 3

The y intercept is 4

which in a gragh it what goes up in the y axis to form a triangle sometimes.

-3x is the slope which is the rise and run of the triangle.
