Question

Is y=x+7 represent a straight line ? Draw the line on the coordinate plane. At which point does this
line intersect Y- axis? How much angle does it make with X - axis ?​

Answer 1

For a line to intersect the Y axis, X must be 0.

In the equation, put x = 0,

Y=0+7 = 7, Hence the point is (0,7)
