Find an equation of the line containing the points (-6,19) and (-15,28)

Answer 1

Hello, find the slope first using the Slope Formula: Y2-Y1/X2-X1

X1=-6
Y1=19
X2=-15
Y2=28

28-19/-15-(-6)
9/-15+6
9/-9
-1

The slope is -1, now use point slope form to determine the equation of the line.

Y2-Y1= M(X2-X1)
M= Slope
X and Y are coordinates above
Y-19= -1(X-(-6)
Y-19=-1(X + 6)
Y-19= -X-6
Y= -X- 6 + 19
y= -X + 13

Hope this helps!
