Write the equation of the line that passes through the points (-7,5) and (0,7). Put your answer in fully reduced point-slope form, unless it is a vertical or horizontal line.

y - 7 = 2/7(x - 0)

Step-by-step explanation:

y=ax +b

a r gradient or incline

You can easily calculate the incline, which is the quotient of (the diffence in y-coordinates) / (diffence in x-coordinates)

a = (7 -5) / (0 - -7) = 2/7

b is the intercept with the y axis , which is difined already by one of the point given.

b = 7

normal form of a line:

y = 2/7x + 7

The fully reduced point-slope form:

y - 7 = 2/7(x - 0)

See attachment for the graph.

option (b) is correct

step-by-step explanation:

to find the solution of this system, we need to convert it into reduced row-echelon form. we have,

after applying row operations r2 -> r2/2 and r3 -> r3/3, we get,
