1. graph y = 2x + 3.

Explanation:

Step1: Find the y - intercept

Set (x = 0). Then (y=2\times0 + 3=3). So the y - intercept is the point ((0,3)).

Step2: Find the x - intercept

Set (y = 0). Then (0=2x + 3), which gives (2x=-3) and (x =-\frac{3}{2}=-1.5). So the x - intercept is the point ((-1.5,0)).

Step3: Plot the points and draw the line

Plot the points ((0,3)) and ((-1.5,0)) on the coordinate plane and draw a straight line passing through them.

Answer:

Graph a straight line passing through ((0,3)) and ((-1.5,0)) on the given coordinate - grid.
