Solving Linear Systems by Substitution

Question 1

First, compute the slopes:

Revolt · Accepted Answer

✔ 0.5; The dinosaur's ribs and arms are at the intersection of the diagonals shown in the diagram. Compute their equations! First, compute the slopes:: 0.5; The dinosaur's ribs and arms are at the intersection of the diagonals shown in the diagram. Compute their equations! First, compute the slopes:: -0.75

Question 2

Slope of m: 0.75✔ -0.751.33-1.33

Revolt · Accepted Answer

✔ -0.75

Question 3

Compute the equations of the lines using point-slope form:

Revolt · Accepted Answer

✔ y - 4 = 0.5(x - 1); Compute the equations of the lines using point-slope form:: y - 4 = 0.5(x - 1); Compute the equations of the lines using point-slope form:: y - 5 = -0.75(x - 43)

Question 4

Line m: y - 43 = -0.75(x - 32)✔ y - 5 = -0.75(x - 43)y - 5 = -0.75(x - 32)y - 43 = -0.75(x - 5)

Revolt · Accepted Answer

✔ y - 5 = -0.75(x - 43)

Question 5

Finally, simplify to slope-intercept form:

Revolt · Accepted Answer

✔ y = 0.5x + 3.5; Finally, simplify to slope-intercept form:: y = 0.5x + 3.5; Finally, simplify to slope-intercept form:: y = -0.75x + 37.25

Question 6

Line m: y = -0.75x - 27.25y = -0.75x - 37.25✔ y = -0.75x + 37.25y = -0.75x + 27.25

Revolt · Accepted Answer

✔ y = -0.75x + 37.25
