Answer:

y = 8x + 19

Step-by-step explanation:

Slope:

  • [tex]\frac{339-19}{40-0}[/tex]
  • [tex]\frac{320}{40}[/tex]
  • [tex]8[/tex]

Slope: 8

Y-intercept:

Input points

  • [tex]339 = 8(40) + b[/tex]
  • [tex]339 = 320 + b\\[/tex]
  • [tex]b = 19[/tex]

Y-intercept: 19

Equation:

y = 8x + 19

-Chetan K

Here the co-ordinates are

  • (0,19)
  • (40,339)

Slope:-

[tex]\\ \tt\hookrightarrow m=\dfrac{339-19}{40-0}=\dfrac{320}{40}=8[/tex]

Equation of line in point slope form

[tex]\\ \tt\hookrightarrow y-y1=m(x-x_1)[/tex]

[tex]\\ \tt\hookrightarrow y-19=8(x)[/tex]

[tex]\\ \tt\hookrightarrow y-19=8x[/tex]

  • Convert to slope intercept form y=mx+b

[tex]\\ \tt\hookrightarrow y=8x+19[/tex]

  • y intercept=b=19
