graph the line that passes through the points (-8,9) and (4,-3) what are the x and y intercepts for this line someone help pleas
VashaNatasha [74]

Answer:

(0,1)- y intercept (1,0) x intercept

Step-by-step explanation:

first lets write this equation in slope intercept form: y=mx+b

m=slope

b=y intercept

so

slope formula:

(y2-y1)/(x2-x1)

y2=-3

y1=9

x2=4

x1=-8

so

(-3-9)/(4--8)=-12/12=-1

slope=-1

hence

y=-1x+b

substitute "x" as 4 and "y" as -3

so

-3=-1(4)+b

-3=-4+b

1=b

so

y=-x+1

1=y intercept

and

0=-x+1

-1=-x

1=x

1=x intercept
