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
