You can put this solution on YOUR website! Find the slope of the line through the given points. Also find the slope intercept form. Find the Y intercept and the X intercept for one of the points.
(-7/5, 3/10) and (1/5, -1/2)
-------------
slope = [(-1/2)-(3/10)]/[(1/5)-(-7/5)] = [-8/5]/[8/5] = -1
--------------------------
To find the equation:
y=mx+b
(-1/2) = (-1)(1/5) + b
b = (-1/2)+(1/5) = -3/10
EQUATION:
y = -x - (3/10)
--------------------
x-intercept:
Let y = 0 and solve for x.
x = -(3/10)
---------------
y-intercept:
Let x = 0 and solve for y
y = -3/10
