This is the equation of a straight line of the form y=mx+c
Here,

m is the slope of the straight line and c is the intercept the line makes on the y axis.

Comparing the given equation y=2x+7 with y=mx+c,
we understand the following:

The line intersects with the y axis at (0,7).

Now we substitute y=0 and solve the equation,
0=2x+7

or 2x=7

or x=72

Hence, the line passes through the point (72,0)
If the two points (72,0) and (0,7) are joined, the required line is obtained.
