About 27 miles. It's 26.666666667
This question does not really make sense.
How ever I’ll try to respond to this with the best of my ability.
y=mx+b is nothing but slope intercept form.
M is slope value. B is the y-intercept.
There is really no need for x-intercepts in slope intercept form.
Hope this helps. :)
You mean the equation: y=-4 this has no slope and the y intercept is 4 or y=-4x this slope is -4 and the y intervept is 0.
