The equation of the line is y = x + 8

The equation of a line is calculated by using the expression!

y - y1 = m(x-x1)

where m is the slope of the line.

The slope of a line is expressed as;

slope = Y - y)/X - x

slope = 10-7)2-(-1)

slope = 3/3 = 1

therefore the slope of the line is 1.

y - 7 = 1( x -(-1)

y - 7 = x + 1

y = x + 1 +7

y = x + 8

Therefore, the equation of the line is y = x + 8
