Without an equation, you know nothing about the slope of a line just because x equals 0. Slope is the change in y value divided by the change in x value over a segment of a line. When you only have a single x value, there is no change so the slope is undefined. Or if you are stating the value of x is 0 for all values of y, then the slope is infinite.

y = x + 0
X=5 is a vertical line, so it has no slope. When I say it has no slope, I don't mean the slope is 0, I mean the slope is nonexistent.
y = x
If: y = 7 then there is no slope and the line will be parallel to the x axis
y = 0That's the equation of the x-axis.Its slope is zero.
y - x = 0 which is the same as y = x + 0 which is of the form y = mx + c where m is the slope and c is the intercept. Hence for y = x + 0, the slope is 1 ans the intercept is 0. The equation represents a line making 45 degrees to the a-axis and it passes through the origin.
Slope = -1
5x-2=0 If "y" is zero then what is "x"? x=2/5 5(2/5)-2=0 If you are asking the slope of 5x-2=y then the slope is 5/1 or five. So if x=1 then y=3 and so on. x=2 y=8 x=3 y=13
y=mx has a slope of m, if the slope is 0, m must be 0. So the coefficient of x is 0.
- 5X + 25Y = 0 25Y = 5X Y = (1/5)X ============
If the line runs parallel to the x axis (horizontally), its slope is 0. If runs parallel to the y axis (vertically), then its slope is undefined. This is because slope equals rise (y) divided by run (x). For example, if the line is raised 0 units on the y scale and runs 3 units over from the origin on the x scale, you calculate slope by dividing 0 (rise) by 3 (run), which equals 0. On the other hand, if we were to flip the units, the case would be different. If you go up 3 units on the y scale, and over 0 units on the x scale, you would divide 3 (rise) by 0 (run), which is undefined because it is impossible to divide by zero.
x=0
y + x = -10Subtract 'x' from each side:y = -x -10The slope is -1 .
put it in slope intercept form... x-y+3=0 -x -x subtract x from both sides of the equation -------------- -y+3=-x -3 -3 subtract 3 from both sides of the equation -------------- -y=-x-3 --- ----- -1 -1 divide both sides of the equation by -1 -------------- y=x+3
Remember the standard form of an equation:Y = (slope) x + (y-intercept)Now take your equationY = (-1) x + (0)Compare yours to the standard one.That's how to find them.Now can you identify the slope and y-intercept of the graph of your equation ?
same x intercept as y = 3x -9 x intercept is when y = 0 0 = 3x-9 3x = 9 x = 3, the same x intercept Now find the line parallel to 3x+y = 0 with x intercept = +3 Since line is parallel it has the same slope 3x+y = 0 y = -3x +0 standard form where the number in front of x is slope, = -3 Thus y = -3x + b but we know x intercept (when y = 0) is +3 0 = -3(3) + b solve b = +9 the parallel line is y = -3x+9
