The 4 on the left side is 10x more than the 4 on the right. This only works if the numbers are next to each other and are the same.
X = - 1/3 or an alternate form x = -0.3, x = -3 to the power of -1
In 1 hr the bus would have traveled 48.5 miles
Parallel line means having the SAME slope
so the slope of a line parallel to the given line is 2
plug in the given point and slope of 2 into point slope form
y+1 = 2 (x+4)
solve for slope intercept form
y+1 = 2x + 8
y = 2x + 7
answer: y=2x+7
