SOLUTION: you are given the following info about a line (0,-3) and (-3,-6).using this info solve for the slope (m) and the y-intercept(b) you are given one coordinate point (1,4) and the

You can put this solution on YOUR website!
points (0,-3) & (-3,-6) define a line as follows:
the slope(m)=(-6+3)/(-5-0)=3/-5 or -3/5
now we substitute one set of points & the -3/5 slope value & solve for the y intercept(b)
-3=-3/5*0+b
-3=b this is the y intercept.
thus the line formula is: y=-3x/5-3 (red line)
--------------------------------------------------------
4=(2/3)*1+b
4=2/3+b
b=4-2/3
b=3 1/3 or 10/3. for the y intercept.
y=2x/3+10/3 (green line)
