Step-by-step explanation:
Equation of straight line: y=mx+b
Given slope=2, hence m=2
y=2x+b
Replace y and x values as stated in the question (-1, -2)
(-2)=2(-1)+b
-2+2=b
b=0
rewrite the equation:
y=2x+0
y=2x
For 3) a solid line is used when the equation is <= or => while dotted line is for when the equation is < or >
Could you elaborate on question 2? I dont quite get what the question is asking for
