PLS HELP WITH 1-2 ASAP

The equation of a line is usually written in the form of y=mx+c, where m is the gradient and c is the y-intercept. This is also known as the slope-intercept form.

How to identify slope and y-intercept:

① Ensure that only the y term is on the left hand side and the x terms and the constant is on the right hand side.

② Make sure that the coefficient of y is 1.

③ The coefficient of x is the slope and the constant is the y-intercept.

Answering from left to right:

Q1) Slope: -2

y-intercept: -1

~

Slope:

y-intercept: 2

~

slope: 1

y-intercept: 0

~

slope: 7

y-intercept: 3

---------------------------------------------------------

Q2)

y= mx +c

1st from the left:

Given that the slope is , m=

Since the y-intercept is -6, c= -6.

Subst m= and c= -6:

~

y= -3x +3

~

4th question for Q2 from the right:

y= 10x + ?

( The y-intercept is not in the picture so substitute that given number into the '?' )

step-by-step explanation:

solution:

as, mean is defined as sum of all the observations divided by total number of observations.

and , median is mid value of the data whether arranged in ascending order or descending order.

consider, roadsters:

2,3,4,5,6,7,8,9

mean =

also, median= , because number of observations is even, so median is mean of two mid values.

now, coming to bandits

2,3,4,5,6

mean =  

median = 4, as number of observations is odd.

so, roadsters has greater median as well mean than bandits.

→option a is true about the repairs performed on 2 types of cars:

bandits have lower median and mean than roadsters.
