What is the equation of the line y = 1/2x - 4 y = 2x - 4 y = 2x + 2 y = 1/2x + 2

The equation of the line is

The equation of a line in slope-intercept form is

y = mx + c

Here m is the slope and c is the y-intercept  

Now  

Here

= (0, 2 ) and = (- 4, 0 )  

Now  

From the graph the y-intercept = (0, 2 ) i.e. c = 2

y = x + 2

the equation of a line in slope-intercept form is

y = mx + c (m is the slope and c the y-intercept )

to calculate m use the gradient formula

m = ( y₂ - y₁ ) / (x₂ - x₁ )

with (x₁, y₁ ) = (0, 2 ) and (x₂, y₂ ) = (- 4, 0 ) ← points from graph

m = = =

from the graph the y-intercept = (0, 2 ) → c = 2

y = x + 2 ← is the equation
