The equation of a line is y-mx+b with m being slope and b being y-intercept. Using the values provided in your problem, your answer would be y=2/3x+9, or C.
Answer:
y = -x+3
Step-by-step explanation:
We have two points so we can find the slope
m =(y2-y1)/(x2-x1)
(1-2)/(2-1)
-1/1
The slope is -1
We can use the slope intercept form of the equation
y = mx+b where m is the slope and b is the y intercept
y = -x+b
Substitute a point into the equation to find b
2 = -1 +b
Add 1 to each side
2+1 =-1+1 +b
3 =b
y = -x+3
Hey man I got u. The answer for this question is B. Peace
Find the change in the y coordinates
7-5=2
Find the change in the x coordinates
1--3 or 1+3= 4
Divide the changes in the y and x coordinates
2/4= 1/2
The slope is 1/2. Hope this helps!
