You can find the slope either by just looking at the line or using the slope formula.
#1: The slope formula is:
Find two points and plug it into the formula
I will use (0, 2) and (1, -1)
(0, 2) = (x₁, y₁)
(1, -1) = (x₂, y₂)

[two negatives cancel each other out and become positive]

m = -3
#2: To find the slope without having to do the work, you use this:

Rise is the number of units you go up(+) or down(-) from each point
Run is the number of units you go to the right from each point
If we start at a defined/obvious point, like (0, 2), find the next point and see how many units it goes up or down and to the right. The next point is (1, -1), so from each point, you go down 3 units and to the right 1 unit. So your slope is -3/1 or -3. You can make sure the slope is right by looking at another point.
Answer:
x=3; x=-3; x=√5; x=-√5
Step-by-step explanation:
I think you are missing something, what expression?
If you mean the • dot, it means multiplication.
Answer:
the x intercept is 2
Step-by-step explanation:
I just went over this unit
7x+4<46
7x+4(-4)<46(-4) <- Subtraction Property of Equality
7x<42
7x(/7)<42(/7) <- Division Property of Equality
x<6
I hope this helps!
