Slope: 1

Y-int: 9

Step-by-step explanation:

In the equation for a linear equation (y = mx + b) m is the slope and b is y-int.

In this equation : y = x + 9, m is the coefficient before the x (1), and the y-int is the 9

m = 1, b = 9

Step-by-step explanation:

y = x + 9 could be (but doesn't have to be) rewritten as y = 1x + 9.

Comparing this to                                                               y = mx + b

quickly reveals the slope:  m = 1, and the y-intercept:  b = 9   (or 0, 9)

walter needs to make at least 5 more cookies but no more than 40. 5 ≤ x ≤ 40

step-by-step explanation:

20 ≤ x + 15 ≤ 55

subtract 15 from all parts

20-15 ≤ x + 15-15 ≤ 55-15

5 ≤ x ≤ 40

this means how many more cookies he has to make

walter needs to make at least 5 more cookies, but no more than 40 cookies; 5 ≤ x ≤ 40

17   x 256=4352
