Find the slope and the y-intercept of the graph of y + 1 = 4/3x

Note that the slope-intercept form is: y = mx + b, in which:

m = slope; b = y-intercept.

Isolate the y. Note the equal sign, what you do to one side, you do to the other.

y + 1 (-1) = 4/3x (-1)

y = (4/3)x - 1

The slope is 4/3

The y-intercept is -1

step-by-step explanation:

9 sandwiches per hour

step-by-step explanation:

when we have a rate, we want a 1 in the denominator

27/3 = 9

27 sandwiches/ 3 hours = 9 sandwiches/hour
