line passes through the point 
 and has a slope of 
 . Write an equation for this line.
Jan 25th, 2015

The main equation for a standard line in slope-intercept form is:

y=mx+b

M is the slope, and b is the y-intercept where the line intersects the y-axis.

The slope is 3, so we replace m with 3. We have y=3x+b. We now need to find the value of b. We can do this by plugging in the point (-3,5).

5=3(-3)+b -> 5=-9+b -> 14=b

So, in the equation, we replace b with 14. We get the final equation of:

y=3x+14.

Hope this helped, thanks!
