A line has a slope of - 10 and includes the points (0,s) and (1, - 6). What is the value of s? s=

Answer 1

Recall that the slope/intercept form of the equation of a line is Y = mX + b

Substituting your slope of -10 and the known point of (1,-6) you can find the value for b. Thus:

-6 = -10 * (1) + b (I use * for multiplication; it's what computers use)

Solving you get

-6 = -10 + b

4 = b

So the full equation of your line is now Y = -10X + 4

Use this equation with the point (0,s) to find the value of s. I will leave that to you. :-)
