Question

If the x-intercept (–68, 0), and the y-intercept (0, –34), what is the equation?

Answer 1

y = -1/2x - 34

or we could write it as 2y = -x - 68

Explanation:

slope = (-34 - 0) / (0- -68) = -34/68

= -1/2

y - y1 = m (x - x1) where m = slope and (x1, y1) is a point on the line , so using slope = -1/2 and the point (-68,0) we have:-

y = -1/2(x - (-68)

y = -1/2 x - 34

Answer 2

Y=-.5x-34

Explanation:

This is because you can do y2-y1/x2-x1 to get slope

-34/68

Which equals one half so currently

Y=-1/2x

To get the y intercept we can look at the number when x=0 so it would be -34. So here is the equation

Y=-.5x-34
