The** y-intercept** of y = 4x - 3 is -3 **same **as in (D) and **slope **of y = -(3/2)x + 2 is -3/2 and **y-intercept **of y = 3x - 2 is 3 **same **as in (G).
What is the equation?
There are many different ways to define an equation . The definition of an equation in **algebra **is a **mathematical statement **that demonstrates the equality of 2 mathematical expressions .
Given the equation ,y = 4x - 3
**Coordinate **of y-intercept is given by (0,y)
⇒ y = 4(0) - 3
y = -3
Now in the option (D) y = -3 + 8x
y-intercept = y = -3
The **slope-intercept **form of an equation is y = mx + c by **comparing **y = -(3/2)x + 2 it is -3/2 which is **present **in equation y = 3x - 2 and y-intercept of y=3x-2 is -2 **same **as y = 3x - 2 in option (G).
Hence "The** y-intercept** of y = 4x - 3 is -3 and **slope **of y = -(3/2)x + 2 is -3/2 and **y-intercept **of y = 3x - 2 is 3 ".

The equation with the same y-intercept as y = 4 x − 3 is D. y = − 3 + 8 x . The equations for the slope of − 2 3 ​ and y-intercept of -2 can be represented by G and H. Both G and H are equivalent forms of the desired equation.
