question 1:
what is the first step to writing an equation in slope-intercept form using the given points: (-1, 0), (-2, -2).
a) use point-slope form
b) substitute -1 for x and 0 for y in y = mx + b
c) find the slope using the slope formula
y2 - y1
x2 - x1
d) find the slope using the slope formula y = mx + b
question 2:
the events x and y have a correlation coefficient of r= 0.02. what is the relationship between x and y?
a) the events have a strong negative linear correlation.
b) the events have a strong positive linear correlation.
c) the events have a weak negative linear correlation.
d) there is little or no linear correlation.
question 3:
camille asked five of her friends how long they studied for the last math test and what grade they received. she found a linear regression equation for the data to be y = 9.6x + 65.8, with x representing hours.
what does the 9.6 and the 65.8 mean in the context of this equation?
a) 9.6 = the lowest score you can get;
65.8 = the highest score you can get
b) 9.6 = the number of points you would increase each hour of studying;
65.8 = your score if you studied 0 hours
c) 9.6 = the number of points you would increase each hour of studying;
65.8 = the highest score you can get
d) 9.6 = the number of hours you studied;
65.8 = your score if you studied 0 hours
question 4:
which ordered pair would not appear as a solution for the linear equation y = βx + 3?
a) (0, 3)
b) (-1, 4)
c) (3, -2)
d) (-7, 10)

Ican interpret and represent the remainder in division calculations sensibly for the context (eg if we wont to know how many 40 seat buses will be needed to transport 170 students for on excursion, we divide 170 by 40 and realise buses and another smaller vehicle to that we need 4 transport 10 more students) solve the following questions. show your work! 11) the zoo had 420 butterflies that needed to be transported to a new enclosure. the boxes that the butterflies would be moved in only hold 80 butterflies in each. how many boxes would they need? 2 12) each classroom in the school can have exactly 25 students, if there are 345 students in the school how many full classrooms are there?
