Answer :
Answer:
d= -5
Step-by-step explanation:
The slope of a line is found by finding the ratio of change is y values to change is x values
[tex]m=y_2-y_1/x_2-x_1[/tex]
The points on the line have coordinates at: (-1,7) (-3,d)
where ;
[tex]y_2=d, y_1=7,x_2=-3,x_1=-1,m=6[/tex]
Applying the formula with values as;
[tex]6=\frac{d-7}{-3--1} \\\\6=\frac{d-7}{-3+1} \\\\6=\frac{d-7}{-2} \\\\6*-2=d-7\\\\-12=d-7\\\\-12+7=d\\\\-5=d[/tex]
The value of d = -5
The coordinates of the points (-1,7) (-3,-5)
