Answer:
Step-by-step explanation:
1. -1+x<-3
add 1
x<-2
-8x+10<-62
subtract 10
-8x<-72
divide by -8(when you divide negative numbers, the sign flips)
x>9
2. 9x-7y= -7
subtract 9x
-7y= -9x-7
divide by -7
y= 9/7x+1
(0,5) (-4,2)
point slope form: y-y1=m(x-x1)
m=slope
slope: (2-5)/-4= -3/4
y-5= -3/4(x)
slope intercept form: y=mx+b
m= slope
b= y-intercept
slope is rise over run
m=1
b=0
y=x
