Question

Find the value of y so that so that the line passing through (4, y) and (5, 3) has a slope of 1.

Answer 1

could any one help I have tried but does not make sens to me thankyou

Answer 2

You already know the slope, you're just missing a y coordinate. so plug everything in and solve for that

1=(3-y)/(5-4)

Answer 3

Can you do it?

Answer 4

thank you for your help got sidetracked.

Answer 5

so its 1= 15-12-5y+4y

Answer 6

1=(3-y)/1
1=3-y
-2=-y
2=y

Answer 7

y= -28

Answer 8

ow i see my mistake now thankyou for your help

Answer 9

-2=x-9 x=7 right?

Answer 10

What?

Answer 11

The question is
Find the value of x so that the line passing through (10, 5) and (x, 9) has a slope of -2.

Answer 12

-2=x-9/-2

Answer 13

-2=(9-5)/(x-10) and solve for x remember the slope formula up there it refers to 2 points
(x1,y1) (x2,y2)

Answer 14

-2=4/(x-10)
-2(x-10)=4
-2x+20=4
-2x=-16
x=8
