Answer:
Step-by-step explanation:
So what you need to do is take the two points (1, -5) and (3, -1) and subtract them. You take y of the second group and subtract y of the first group.
-1 - (-5) = 4
Now you do the first numbers in each group with the second set being the number you subtract from.
3 - 1 = 2
Now you do . Rise = 4 Run = 2
= 2
Now the second part is saying y = 3x + c with your first set of numbers being x and y.
x = 1
y = -5
-5 = 3(1) + c
-5 = 3 + c
Subtract 3 from -5
-8 = c
The final answer is:
y = 3x - 8
Check the picture below.
using a second for it, since it's a horizontal line, then say hmmm we'll use the y-intercept, or (0, 1), so the equation of a line that passes through (2,1) and (0,1)
