Well you need to have two points to find the equation of a line and you've only given one point with the coordinates (-5, -10). I would recheck the question to see if it gave a y-intercept, which would give us another point, and make this solvable.
Since you've given only one point, I am going to assume that the line passes through the origin at point (0, 0)
If this is the case then do rise over run to find slope -10/-5 = 2
The classic way to write out the equation of a line is y = mx+b
y = mx + b
y = 2x + 0 (slope is 2, and if the line does pass through the origin then b is 0)
y = 2x
If the slope is undefined, then its a vertical line (up and down) .So draw a vertical line (up and down) that goes through -2 on the x-axis.
Points: (2, -3) and (-2, 0) Slope: -3/4 Equation: y = -0.75x-1.5
The parallel equation works out as: 4y = 3x+1 which can be expressed in the form of 3x-4y+1 = 0
Point is not an undefined term. It can be defined as a mathematically precise location, or as the place where two lines intersect.
It is a straight line equation with no x or y intercepts on the Cartesian plane
If the slope is undefined, it is a vertical line. Therefore the equation is x=2.

You can have infinitely many lines through one specific point, each with a different equation. If you want to have a general equation for ANY line that goes through that point, use the point-slope equation for a line, and use a variable for the slope.
If the slope is undefined, then its a vertical line (up and down) .So draw a vertical line (up and down) that goes through -2 on the x-axis.
If you mean a slope of 6 passing through the point of (1, 3) then the equation works out as: y = 6x-3
x = 1 (the line intersects the x-axis at 1, and is parallel to the y-axis)We cannot write the equation on the Slope-intercept form, since the slope of the line is undefined. 1 is the x-coordinate of any point on the given line.
If you mean a point of (-1, 4) and a slope of -3 then the equation is y = -3x+1
It is x + 3 = 0.
Because of undefined slope, because undefined slope does not have a slope it doesn't have anything to substitute for m in the point slope equation.

It is the equation of a line passing through the point (0, 1/3) and with slope 4/3
If you mean passing through (1, 2) with a slope of -3 then it is y = -3x+5
