graph the equation y = 2x - 3
step 1
To graph a line we need at least two points
so
Find the intercepts
y-Intercept (value of y when the value of x is equal to zero)
For x=0
y=2(0)-3
y=-3
the y-intercept is the point (0,-3)
x-Intercept (value of x when the value of y is equal to zero)
For y=0
0=2x-3
2x=3
x=1.5
the x-intercept is the point (1.5,0)
step 2
Plot the intercepts and join them to graph the line
using a graphing tool
see the attached figure
