Answer:
slope is -1
Step-by-step explanation:
Slope of the line (m)=(y2 -y1)/(x2 -x1)
given
(x1, y1)=(-4 , 5)
(x2,y2)=(-7 , 8)
Now using the above formula
m =(8-5)/(-7-(-4))
m = (3)/(-7+4)
m= 3/(-3)
m=-1
therefore the slope of the line is -1
First, simplify the equation to slope intercept form to find the slope;
2x+3y=4
3y=4-2x
y=(-2x+4)/3
The slopes of parallel lines are the same, therefore, the slope of the second line would also be -2/3
Write out the slope intercept form with the information we know and input the coordinates of the point;
y=mx+c
-4=(-2/3)(1)+c
-4+(2/3)=c
(-12/3)+(2/3)=c
-10/3=c
Therefore, the final equation is y=-2/3x-10/3
