Answer:

y = 2/3x - 7

Step-by-step explanation:

(3, -5) (-3, -9)

and y = -7 when x = 0  from graph

so c = -7

m = -9 - (-5)  / -3 - 3

= -4 / -6

= 2/3

line equation is y = mx + c

y = 2/3 x + (-7)

y = 2/3x - 7

[tex]\\ \sf\longmapsto m=\dfrac{-9+5}{-3-3}[/tex]

[tex]\\ \sf\longmapsto m=\dfrac{4}{6}[/tex]

[tex]\\ \sf\longmapsto m=2/3[/tex]

  • b=-7

Now

Equation of line

[tex]\\ \sf\longmapsto y=mx+b[/tex]

[tex]\\ \sf\longmapsto y=\dfrac{2}{3}x-7[/tex]
