Answer:
The equation of the line is 4y = -x + 19
Step-by-step explanation:
Firstly, we need to get the slope of the line;
Since it is through two points; we have the slope as;
y2-y1/x2-x1 = (5-3)/(-1-7) = 2/-8 = -1/4
Mathematically, we can write the equation of a straight line line as;
y = mx + c
So we have;
y = -1/4x + c
y = -x/4 + c
To complete the equation, we need the value of c.
we can choose any of the points and insert the x and y value
Thus;
3 = -7/4 + c
c = 3 + 7/4
c = 19/4
So our equation becomes;
y = -x/4 + 19/4
Multiply through by 4
4y = -x + 19
Answer:
y-3= -1/4 x (x-7)
Step-by-step explanation:
Find the slope of the line between
( 7 , 3 ) (7,3) and ( − 1 , 5 ) (-1,5) using m = y 2 − y 1 x 2 − x 1
m=y2-y1x2-x1 , which is the change of y/ y over the change of x/ x .
Hope this helps! Have a nice day!❤
