Match each slope and y-intercept with the appropriate linear equation.
Bumek [7]

Answer:

m= 4, b = 3 matches with y = 4x +3

m=5, b = -2 matches with y = 5x - 2

m = 3, b = 4 matches with y = 3x + 4

m = -2, b=5 matches with y = -2x + 5

Step-by-step explanation:

Slope-intercept form is <em>y = mx + b</em><em> </em>in which m = slope and b = y-intercept

Answer:

61°

Step-by-step explanation:

Alright so the total amount of degrees in a 5-sided shape or pentagon is 540°. Since we have four of the five total angles, we can solve for the last one.

Sum of all the degrees of all five angles = 540°

The variable x is representing our last unknown degree.

90° + 107° + 144° + 138° + x° = 540°

Add up all the known degrees and solve for x.

479° + x° = 540°

Subtract 479 on both sides so that we can isolate x.

479° + x° - 479° = 540° - 479°

x° = 61°

So our final answer is 61°
