Front

What does the b stand for in y=mx+b?

Back

b represents the y-intercept, which is the value of y when x is 0.

Front

In the equation y = 2x + 3, how many tiles does figure 0 have?

Back

Figure 0 has 3 tiles.

Front

What is the rule for the number of tiles in a pattern if y = 5x + 7?

Back

The rule indicates that for each figure x, the number of tiles y is calculated as 5 times x plus 7.

Front

How many tiles are in Figure 0 for the equation y = 5x + 7?

Back

There are 7 tiles in Figure 0.

Front

What is the growth in the equation y = 4x + 5?

Back

The growth is 4, which is the coefficient of x.

Front

What does the slope (m) represent in the equation y=mx+b?

Back

The slope (m) represents the rate of change of y with respect to x.

Front

If y = 3x + 2, what is the y-intercept?

Back

The y-intercept is 2.

Front

In the equation y = 6x + 1, how many tiles does figure 0 have?

Back

Figure 0 has 1 tile.

Front

What is the value of y when x = 4 in the equation y = 5x + 7?

Back

When x = 4, y = 5(4) + 7 = 27.

Front

If y = 2x + 5, what is the value of y when x = 0?

Back

When x = 0, y = 2(0) + 5 = 5.
