Step-by-step explanation:
I can give you the formulas and how to do it.
The formula for finding the slope is
y²-y¹ all over(divided by) x²-x¹.
You take the order pairs and you label them.
For example, the first one.
(4,2) 4 can be x¹ and 2 can be y¹
(7,6.5) 7 can be x² and 6.5 can be y²
So then you plug it in.
(6.5-2) all over/divided by (7-4)
That ends up being 4.5 over 3. Fraction form.
That is your slope.
Then you plug the slope into the point-slope formula which is
y-y¹=M(x-x¹).
You plug your slope in for M.
You pick either of the given points and plug it in for y¹ and x¹.
Then you solve.
If done right, your formula will end up matching the slope-intercept formula
y=Mx+b.
M is your slope.
b is your y-intercept.
Dont freak out when you start doing it with fractions. Just because it looks wierd, doesnt mean it's wrong.
Use this process for all four.
Hope this helps.
