Question

write an equation for the line with x-intercept 3 and y-intercept 2/3

y=mx+b

2y/3 =1/3x+b

but how do i find my b?

show all working please

Answer 1

y=-2x/9+2/3

Answer 2

whn x intercepts y = 0

so

2y/3 =1/3x+b

2(0)/3 =1/3(3)+b

0 = 1 +b

b = -1

Answer 3

now whts that?

Answer 4

m=-b/x

Answer 5

no?

Answer 6

no thats not how we solve it my apologies

Answer 7

this is the double intercept so we use the formula x/a+y/b=1

where a is the x-intercept and b is the y-intercept

Answer 8

x/3+3y/2=1

y=-2x/9+2/3

Answer 9

thanks still saifoo.khan

Answer 10

You are provided with 2 points P1(0,2/3) and P2(2,0)
Use the formula for slope m=(y2-Y1)/(x2-x1)=(0-2/3)/(2-0)=(-2/3)/2=-1/3

Answer 11

Slope is as shown -1/3
Now pick one of the points and use the formula y=mx+b
using the point P1(0,-2/3) plug in those values
-2/3=-1/3(0)+b
b=-2/3
y=-2/3x-2/3
