y+=+-2x+-+7
If the equation of the line is given in the slope intercept form y=mx%2Bb, then m is the slope
y+=+-2x+-+7 the slope is m=-2
x-intercept: Let y+=+0, substitute in place of y and then solve for x: 0=-2x-7, 2x+=-7, x=-3.5.
y-intercept: Let x+=+0, substitute in place of x and then solve for y: y+=+-7
