Can i have the answer to this <br> pic is below
eduard

Answer:

question 1: m = 3/2

question 2: m = 1/95

Step-by-step explanation:

Slope intercept form of equation is of form

y = mx+c

where m is the slope of line and c is the y intercept of the line.

Y intercept is point on y axis where the line intersects the y axis.

____________________________________

given

y = 3/2 x

comparing it with y = mx+c

we have m = 3/2 .

since y = 3/2 x does not have constant term so it can be taken as 0. hence c is 0

_________________________________________

slope for any two point (x1,y1) and (x2,y2) on coordinate plane is given by

slope = (x2-x1)/y2-y1)

From the given table lets take two point as (2,190) and(4,380)

Thus, slope m is given by

m = (4-2)/(380-190) = 2/190 = 1/95

m = 1/95

Though, slope can be taken by dividing y by x (y/x). It is good practice to use two point form formula as given above . Provided two points are given

Please mark it the brainliest.

timama [110]

Step-by-step explanation:

<u>Using Pythagorus theorem</u> :

(A)

PR =  \sqrt{ {PQ}^{2}  +  {QR}^{2} }

PR =   \sqrt{196 + 81}  =  \sqrt{277}  = 16.64 \: cm

(B)

QR  =   \sqrt{ {PQ}^{2}  +  {PR}^{2} }  =  \sqrt{196 +324 }  = 22.8 \: cm
