The slope is -4
y = 0.75x+0.5 For the equation to be parallel the slope must be the same but the y intercept must be different
The slope is 5. Parallel lines always have the same slope.
The slope is -0.2
There is no "equals" sign therefore "x-9" is NOT an equation.
Without an equality sign it is not an equation but when a straight line equation is parallel to another straight line the slope remains the same but the y intercept is different
If you mean y = 2x-3 then the parallel equation will have the same slope of 2 but with a different y intercept
Parallel, the slope of the second equation is 4
x = -3 represents a vertical line whose slope is undefined.
