Answer:
Step-by-step explanation:
Find the slope of the line that passes through the points (-1,7) and (2.4):
So, the equation of the line is
where are the coordintaes of the point from the line
or
where b is y-intercept.
To find b, substitute x = -1 and y = 7:
If then
If then
So correct options are
Let us say, the number is "a"
one less than "a" is ... well a - 1
2/5 of that will be... well, 2/5 * ( a - 1)
one more than "a" is... well a + 1
3/5 of that is.. hmmm 3/5 * (a + 1)
now, we're told that, the first expression is "less than" the second one, thus
solve for "a", or make it "x" if you wish, same thing anyway
