Question 14)y-intercept is the point where the value of x is zero. So if we substitute x=0 in the given equation, we can find the y-intercept of the given equation.
Equation is:
7x - 3y = -14
Using x = 0, we get:
7(0) - 3y = -14
-3y = -14
so,
y = 14/3
Thus, the y-intercept will be (0,14/3)Question 15)
In order to convert the given equation to slope intercept form, we isolate y on left hand side of the equation and the rest of the terms on right hand side of the equation.
The above equation is the slope intercept form of the equation. So option D gives the correct answer
