Answer:
Part 1) The equation in slope intercept form is 
Step-by-step explanation:
Part 1) Write an equation in slope-intercept form for a line that passes through (3,4) (and has a y intercept of -8)
we know that
The equation of a line in slope intercept form is equal to

where
m is the slope
b is the y-intercept
we have


substitute

solve for m



therefore

The answer is $300 because you have to multiply 25x12. 10x25=250 and 2x25=50. 250+50=300.
0.88......ones (decimal), tenths, hundredths
so 8 is in the tenths place....8/10
