the equation of each line using the given y- intercept and x- intercept
is
Given :
given the y- intercept and x- intercept . y intercept ( 0, -2) and x intercept is (-3, 0)
We need to frame the equation of the line y=mx+b
where m is the slope and b is the y intercept
y intercept is (0,-2) so the value of b=-2
Now we find slope using two points (0,-2) and (-3,0)
Apply slope formula
We got the slope m and y intercept b =-2
Replace it in y=mx+b to get the equation of the line
