Answer:

a. Slope (m): ⅓

b. y-intercept (b): 5

c. Equation: y = ⅓x + 5

Explanation:

3a. Using two pairs from the table, say, (-3, 4) and (0, 5):

Slope = m = ∆y/∆x = (5 - 4)/(0 -(-3)) = 1/3

m = ⅓

b. y-intercept (b) is the value of y, when x = 0.

Thus, from the table, when x = 0, y = 5.

Therefore, y-intercept (b) = 5

c. Substitute m = ⅓, and b = 5 into y = mx + b

The equation is:

y = ⅓x + 5
