Answer:
y = 3x + 3
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Calculate m using the slope formula
m = (y₂ - y₁ ) / (x₂ - x₁ )
with (x₁, y₁ ) = (- 1, 0) and (x₂, y₂ ) = (0, 3)
m = 
= 3
We are given the y- intercept, that is c = 3
y = 3x + 3 ← equation of line
This pentagon can be split into three triangles, so the total for this pentagon is 540°. Add up all angles to equal 540°.
x= unknown angle
90° + 107° + 144° + 138° + x= 540°
479 + x= 540
subtract 479 from both sides
x= 61
CHECK:
90 + 107 + 144 + 138 + 61= 540
540= 540
ANSWER: x= 61°
