Answer:
15/4 x-y=-24
Step-by-step explanation:
the standard form is ax+by=c
two points (x1,x2) , (y2,y1)
x1=-8 x2=-6
y1=-4 y2=9
find slope m: y2-y1/x2-x1
m=9-(-6)/-4-(-8)
m=15/4
find b: take any point(-8,-6)
y=mx+b
-6=15/4 (-8)+b
-6=-30+b
b=-6+30
b=24
y=15/4 x+24
standard form: y-15/4x=24
OR : 15/4 x-y=-24

Answer:
y=1; x=2
Step-by-step explanation:
Substitution:
x=2y
2x+5y=9
=> if x=2y, plug in the x value into other equation, so
----------------------------------------------------------------------------
2(2y)+5y=9
4y+5y=9
9y=9
y=1
You have the Y value, so now solve for X
-----------------------------------------------------------------------
plug in y value to x=2y
so x=2(1)
x=2
Answer:
6. 62
7. 72
8. 78
9. 57 = -4 ??
10. ??
Step-by-step explanation:
6. 7*8 = 56, 56+6 = 62
