Algebra Problems


ALGEBRA:
QUESTION: 27
Graph for the given. Slope m = -1 and y-intercept b = 6
Solution:
We can find the x intercept using the given slope and y intercept.
y-intercept is 6 so, it is (0,6)
to find x intercept use the formula,
y2-y1
-------   = m = slope
x2-x1.
Take x intercept as (x,0)
Here apply the x and y intercept values in the formula  to find the x intercept of the equation.
          6-0
          -----   =  -1
          0-x
Solve for x, we will get x =6.
So, here we found x intercept as (6,0)
Now, we can draw Graph for these x and y intercepts.
