If you want to find the equation of line with a given a slope of 8 which goes through the point (0,6), you can simply use the point-slope formula to find the equation:


---Point-Slope Formula---

y-y%5B1%5D=m%28x-x%5B1%5D%29 where m is the slope, and is the given point


So lets use the Point-Slope Formula to find the equation of the line


y-6=%288%29%28x-0%29 Plug in m=8, x%5B1%5D=0, and y%5B1%5D=6 (these values are given)


y-6=8x%2B%288%29%280%29 Distribute 8


y-6=8x%2B0 Multiply 8 and 0 to get 0


y=8x%2B0%2B6 Add 6 to both sides to isolate y


y=8x%2B6 Combine like terms 0 and 6 to get 6

Answer:


So the equation of the line with a slope of 8 which goes through the point (0,6) is:


y=8x%2B6 which is now in y=mx%2Bb form where the slope is m=8 and the y-intercept is b=6


Notice if we graph the equation y=8x%2B6 and plot the point (0,6), we get (note: if you need help with graphing, check out this solver)


Graph of y=8x%2B6 through the point (0,6)
and we can see that the point lies on the line. Since we know the equation has a slope of 8 and goes through the point (0,6), this verifies our answer.
