If you mean: x+y = 90 then y = -x+90 which is in slope intercept form
If you mean x-y = 5 then y = x-5 whereas it has a slope of 1 and a y intercept of -5
If you mean: y = x+3 then the slope is 1 and the y intercept is 3
If you mean: x-2y = 2 then it is y = 0.5x-1
A line with a y-intercept but no x-intercept will be a straight line parallel to the x axis. It will have a slope of zero.
A vertical line does not have a slope - negative or positive. It is not defined. A vertical line has no y intercept and, if its equation is x = c (for some number c), then the x-intercept is (c, 0).
If you mean: x+y = 90 then y = -x+90 which is in slope intercept form
If you mean x-y = 5 then y = x-5 whereas it has a slope of 1 and a y intercept of -5
If you mean: y = x+3 then the slope is 1 and the y intercept is 3
If you mean: x-2y = 2 then it is y = 0.5x-1
Slope is -1 y-intercept is 1 x-intercept is 1
A line with a y-intercept but no x-intercept will be a straight line parallel to the x axis. It will have a slope of zero.
Slope is zero y-intercept is -7 there is no x-intercept for this equation
If: x+2y = -1 then y = -1/2x -1/2 whereas -1/2 is the slope and -1/2 is the y intercept
The slope is -1.25
The answer depends on the signs of the original intercepts.x negative, y negative: negative slope becomes less negative and could go positive.x negative, y positive: positive slope becomes greater.x positive, y negative: positive slope becomes less positive and could go negative.x positive, y positive: negative slope becomes more negative.For 1 and 3, the slope changes sign when the y intercept crosses the origin.
If you mean: (0, 11) then y = x+11
