The slope-intercept form of an equation of a line:
m - slope
b - y-intercept
We have the equations in the standard form. Convert to the slope-intercept form:
<em>subtract 3x from both sides</em>
<em>add x to both sides</em>
<em>divide both sides by 3</em>

We need only two points to plot a graph of each function.
for x = 0 and for x = -3:
for x = 0 and for x = -3:
Look at the picture.
By solving the linear equation it can be obtained that
The value of x is 2
What is a linear equation?
At first it is important to know about equation
Equation shows the equality between two algebraic expressions by connecting the two algebraic expressions by an equal to sign.
A one degree equation is known as linear equation.
The given linear equation is
0.3 = 0.5x - 0.7
0.5x = 0.3 + 0.7
0.5x = 1
x =
x = 2
The solution of this linear equation is x = 2
