I assume the question should be y = -2x + 5? The equation of a line that is parallel to that line is any line that begins 7 = -2x ... after the -2x any number may be added or subtracted. Parallel lines have the same slope. In the original equation, the slope is -2.
There is a standard equation for a straight line. It is y = mx + b. m is the slope and b is the y-intercept (when x = 0). In the question m = -4 and is therefore the slope of the line represented by the equation y = -4x + 7.
The slope, or the change in y in respect to x, can be found by putting the equation into y = mx + b form. Y = (9/5) x - 4/5 The slope is m or (9/5). Any equation in y intercept form with that slope is parallel.
Which of the following is the point-slope equation of the line with a slope equals -4 and a point of -2 3?
Slope = 4
q2
-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 -4
The slope is 5. Parallel lines always have the same slope.
The slope is -0.2
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
There is no "equals" sign therefore "x-9" is NOT an equation.

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
Y = -2x + 5 so the slope of this equation, along with the slopes of parallel equations, is -2
