Aline passes through (9, –9) and (10, –5).write an equation for the line in point-slope form.
rewrite the equation in standard form using integers.
a) y + 9 = 4(x + 9) ; -4x + y = -45
b) y - 9 = 4(x + 9) ; -4x + y = 45
c) y - 9 = 4(x + 9) ; -4x + y = -45
d) y + 9 = 4(x + 9) ; -4x + y = 45
^^ the options look pretty similar, so make sure you're answering correctly! you : )

The customer price index(cpi), which measures the cost of a typical package of customer goods,was 208.8 in 2011 and 244.1 in 2016.let x=11 corresponding to the year 2011 an estimate to cpi into 2013 and 2014. assume that the data can be modeled by a straight line and the trend to continue idenfinitely.use data points to find such a line and then estimate the requested quantities

White shapes and black shapes are used in a game. some of the shapes are circles. while the rest are squares. the ratio of the number of white shapes to the number of black shapes is 5: 11. the ratio of the number of white cicrles to the number of white squares is 3: 7. the ratio of the number of black circles to the number of black squres is 3: 8. work out what fraction of all the shapes are circles.
