Answer:

  • y = x + 5

Step-by-step explanation:

Use two points from the green line to determine its equation.

Points:

  • (0, 5) and (3, 8)

Slope-intercept form:

  • y = mx + b

Find the slope:

  • m = (8 - 5)/(3 - 0) = 3/3 = 1

The y- intercept is b = 5

The line is:

  • y = x + 5

Take 2 points

  • (2,7)
  • (1,6)

[tex]\\ \rm\hookrightarrow m=\dfrac{6-7}{1-2}=-1/-1=1[/tex]

Equation in point slope form

[tex]\\ \rm\hookrightarrow y-7=x-2[/tex]

  • Convert to y=mx+b

[tex]\\ \rm\hookrightarrow y=x+5[/tex]
