The straight line equation would depend on the slope which has not been given.

If you mean a slope of -2 passing through (5, 0) then the equation is y = -2x+10
The general equation of the line is y = 3x + c. Having only one coordinate (21) of a point on this line is not enough to evaluate c.
It is: y = 5x+6
If you mean a slope of -4 passing through (-2, 6) then it works out as y = -4x-2
39
If the slope is m, then the equation is y - 7 = m*(x + 3)
Slope: -35 passing through (-5, -1) Equation: y = -35x-176
If you mean a point of (-1, 4) and a slope of -3 then the equation is y = -3x+1
30
If you mean a slope of -2 passing through (5, 0) then the equation is y = -2x+10
If the slope is undefined, it is a vertical line. Therefore the equation is x=2.
y=x
It is: y--3 = -4(x--8) which works out as y = -4x-35
The general equation of the line is y = 3x + c. Having only one coordinate (21) of a point on this line is not enough to evaluate c.
It is: y = 5x+6
If you mean passing through (1, 2) with a slope of -3 then it is y = -3x+5
