Question 1
2u
aisha and carolina each sketch a graph of the linear equation y
aisha uses the equation y= 22 +2,
to sketch the graph
and
carolina uses the equation y = 22 +2
a. explain how this leads them to use different steps to construct their graphs.
aisha identifies the y-intercept as - 3, and carolina identifies the y-intercept as 3.
aisha identifies the y-intercept as 4, and carolina identifies the y-intercept as -4.
when they use the slope to plot the second point, aisha moves down 3 units and right 4 units while
carolina goes up 3 units and left 4 units.
when they use the slope to plot the second point, aisha moves left 3 units and up 4 units while
carolina goes right 3 units and down 4 units.

in the attachment.   i didn't see your choices.   the word which means there is choices.

step-by-step explanation:

(x,y)

x tells you how much left or right you go from the origin

y tells you how much down or up you go from the origin

so for example (-3,2), you go left 3 and up twice. i denoted which of the ordered pairs is which in my graph.

answer:   35 % is the probability of a late departure or an early arrival.

step-by-step explanation:

let l represents the late departure and e represents the early departure.

then, according to the question,

p(l) = 12 %,   p(e) = 27 % and = 4 %

and, we have to find out,

but, we know that,

which is the required equation that will use to find the probability of a late departure or an early departure.

therefore,   the probability of a late departure or an early arrival =   35 %
