Answer: y = -4x + 3

Step-by-step explanation:

y = mx + b

=> y = -4x + b

Find "B":

y = -4x + b

=> 3 = -4(0) + b

=> b = 3

so y = -4x + 3

deff fn [24]

Answer:

x = 44 degrees.

Step-by-step explanation:

Hi!

Since m<2 and m<3 equal 180 degrees (sum of flat line), we can form an equation

(x+4) + (3x) = 180

x + 4 + 3x = 180

4x + 4 = 180

4x = 176

Divide by 4 on both sides

x = 44 degrees
