Quiz#2

Consider the equation:
y = -5x + 4
Identify the slope and y-intercept.

• m = 4, b = x

• m = -5x, b = 4

• m = 5, b = 4

• m = -5, b = 4

Which equation matches the graph?

• y = 2x

• y = 1/4 x + 2

• y = 1x + 4

• y = 2x - 3

The graph of a linear function is shown on the grid. Which equation is best represented by this graph?

What is the equation of the line shown?

• y = 6
