Answer:
Step-by-step explanation:
Here, we want to graph the given equations
1. y = 2x - 3
The general form of the equation of a straight line is;
y = mx + b
m is the slope and b is the y-intercept
To plot the line, we need the x intercept and the y-intercept
At the x-intercept, the value of y is zero
at the y-intercept . the value of x is zero
From the equation, we have the y-intercept as -3
To get the x-intercept, set y = 0
0 = 2x - 3
2x = 3
x = 3/2
x = 1.5
so to graph the line, we have to join the points ;
(0,-3) and (1.5,0)
b) y = -3x + 2
The y-intercept is 2
To get the x intercept, set y = 0
0 = -3x + 2
3x = 2
x = 2/3
so, we have to join the points (2/3,0) and (0,2)
We have the lines plotted as an attachment
