Write Equation Based On The Graphdraw The Problem Or Calculate It class=

Sagot :

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
