The equation must be written in slope-intercept form
y= mx +b
m= slope
b= y-intercept (where the line crosses the y-axis)
to find the slope apply the slope formula:
[tex]m=\frac{y2-y1}{x2-x1}[/tex]
Use the points from the graph:
(x1,y1) = (-5,-4)
(x2,y2)= (5,2)
Replace
[tex]m=\frac{2-(-4)}{5-(-5)}=\frac{2+4}{5+5}=\frac{6}{10}=\frac{3}{5}[/tex]
The line crosses the y axis on y=-1
b=-1
Equation:
y= 3/5x -1
