Question

Write the equation of the line that passes through the points (-3, 4) and (-3,3)​

Answer 1

Answer:

first determine the gradient because the equation of a straight line is y=mx+c

therefore gradient=change in y/change in x

=y2-y1/x2-x1

=4-3/-3-(-3)

=1/0

there fore gradient of the line is undefined

y=x+c

4=-3+c

4+3=c

7=c

therefore y=x+7
