Completet the equation of the line through(3,1) and (4,7)

Step-by-step explanation:

GIVEN POINTS

( 3 , 1) and ( 4 , 7)

First calculating slope (m)

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

= ( 7 - 1) /(4 - 3)

= 6/1

= 6

Now the equation of line is given by

y - y1 = m(x - x1)

y - 1 = 6 ( x - 3)

y - 1 = 6x - 18

6x - y = - 1 + 18

6x - y = 17

6x - y - 17 = 0

Hope it will help :)

the circle one

option c) graph of line going through 1, 4 and 3, 10

step-by-step explanation:

let y equal to margo's coin collection

let x equal to number of years

at the begining x=0, y=1 → point=(x,y)→point=(0,1)

she adds 3 coins per year, then y=1+3x

at x=1, y=1+3(1)=1+3→y=4→point=(x,y)→point=(1,4)

at x=3, y=1+3(3)=1+9→y=10→point=(x,y)→point=(3,10)

the graph of line going through (1, 4) and (3, 10), then the option c is the correct.
