Answer:

The linear equation of the graphed line:

  • y = 7/2x - 3.5

Step-by-step explanation:

Given the points from the graph

  • (1, 0)
  • (3, 7)

Finding the slope between the points

[tex]\mathrm{Slope}=\frac{y_2-y_1}{x_2-x_1}[/tex]

[tex]\left(x_1,\:y_1\right)=\left(1,\:0\right),\:\left(x_2,\:y_2\right)=\left(3,\:7\right)[/tex]

[tex]m=\frac{7-0}{3-1}[/tex]

[tex]m=\frac{7}{2}[/tex]

We know the slope-intercept form of the line equation

[tex]y=mx+b[/tex]

Where m is the slope and b is the y-intercept

substituting m = 7/2 and the point (1, 0) to find the y-intercept 'b'

y=mx+b

0 = 7/2(1) + b

0 = 7/2 + b

b = -7/2

b = -3.5

Thus, y-intercept 'b' = -3.5

substituting m = 7/2 and the y-intercept 'b' = -3.5 in the slope-intercept form

[tex]y=mx+b[/tex]

y=7/2x + (-3.5)

y = 7/2x - 3.5

Thus, the linear equation of the graphed line:

  • y = 7/2x - 3.5
