Scenario: A kid initially has 7.6 dollars and is given 0.2 dollars every weekend. The slope here is the 0.2. This is the value or increment in which the money is increasing. The y-intercept is the value we obtain from the equation when we set x to zero. Similarly speaking, this is the original value which is 7.6.
Are you looking for the value of x?
We can complete the square/factor:
x^2+7x-30=0
(x+10)(x-3)=0
By the zero product property rule, we have two equations, x+10=0 and x-3=0.
So the zeroes of x are -10 and 3
Hope this helped. Comment below if this didn't make sense.
