The given line has slope-intercept equation y = 4x-7;
the slope of the given line is 4;
any line parallel to the given line also has a slope of 4;
the equation of any line parallel to the given line has a slope-intercept equation of the form y=4x+b

Determine the value of b using the given required point (x,y) = (0,0):

y = 4x+b
0 = 4(0)+b
0 = 0+b
b = 0

The slope-intercept form of the specified equation is y = 4x+0, or just y = 4x.

ANSWER: y = 4x

given:
y=4x-7
P(0, 0)
find: an equation of the line that passes through the given point and is parallel to the given line
recall that parallel lines have same slope
since a slope of given line is 4, an equation of parallel line so far is
y=4x%2Bb......use given point to find b
0=4%2A0%2Bb
b=0
equation of parallel line is y=4x
