The equation of line that passes through the points (-3,-1) and
(-6,3) is:
[tex]y=-\frac{4}{3}x-5[/tex]
Step-by-step explanation:
Given points are:
(-3,-1) =(x1,y1)
(-6,3)=(x2,y2)
The slope-intercept form of equation of line is:
[tex]y=mx+b[/tex]
We have to find the slope first
[tex]m=\frac{y_2-y_1}{x_2-x_1}\\=\frac{3-(-1)}{-6-(-3)}\\=\frac{3+1}{-6+3}\\=\frac{4}{-3}[/tex]
Putting the value of slope in the slope intercept form
[tex]y=-\frac{4}{3}x+b[/tex]
To find the value of b, putting the point (-3,-1) in the equation
[tex]-1=-\frac{4}{3}(-3)+b\\-1= 4+b\\b=-4-1\\b=-5[/tex]
Putting the values of b and m
[tex]y=-\frac{4}{3}x-5[/tex]
The equation of line that passes through the points (-3,-1) and
(-6,3) is:
[tex]y=-\frac{4}{3}x-5[/tex]
