Write the equation of a line that passes through (-1, -2) and has a slope of 2 in point-slope form.
1 answer:
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

Answer:
The answer is y= -1/3x-5
Step-by-step explanation:
(9, -8) and (-6, -3)
m= y²-y¹/x²-x1
m= (-3)-(-8)/(-6)-9
m= 5/-15
m=-1/3
y=mx+b
y=-1/3x+b
-3=-1/3(-6)+b
-3=2+b
-2 -2
-5=b
The answer is y=-1/3x-5
