Type an equation for the line
Thepotemich [5.8K]

Answer:

y=-\frac{2}{3}x+1

Step-by-step explanation:

Let the equation of the line given in the graph is,

y = mx + b

Where 'm' is the slope of the line

And 'b' represents the y-intercept

Since slope of a line passing through two points (x_1, y_1) and (x_2,y_2) is modeled by,

m = \frac{y_2-y_1}{x_2-x_1}

If this line passes through (-3, 3) and (3, -1),

m = \frac{3+1}{-3-3}

m = -\frac{4}{6}

   = -\frac{2}{3}

And 'b' = 1

Equation of this line will be,

y=-\frac{2}{3}x+1
