Answer:

  • C. y = 4x - 3

Step-by-step explanation:

The line has a positive slope and negative y-intercept.

  • m = 4, b = - 3

This is only matched by a choice C

Take 2 points

  • (0,-3)
  • (1,1)

Slope:-

[tex]\\ \sf\longmapsto m=\dfrac{1+3}{1}=4[/tex]

Equation of line in point slope form

[tex]\\ \sf\longmapsto y-y_1=m(x-x_1)[/tex]

[tex]\\ \sf\longmapsto y+3=4x[/tex]

[tex]\\ \sf\longmapsto y=4x-3[/tex]
