Answer:
For the line represented by y = 5 x − 7, the slope is 5 and the
y-intercept is -7.
Step-by-step explanation:
The equation is in <em>Slope-intercept form</em>.
The letter 'm' represents the slope.
The letter 'b' represents the y-intercept.
In the equation 
:
- 5 is the slope because it replaces 'm' in the equation. The 'm' is the slope.
- -7 is the y-intercept because it replaces 'b' in equation. The 'b' represents the y-intercept.

Problem: 2x^2+3x-9
For a polynomial of the form, ax^2+bx+c rewrite the middle term as the sum of two terms whose product a·c=2·-9=-18 and whose sum is b=3.
Factor 3 out of 3x
2x^2+3(x)-9
Rewrite 3 as -3 plus 6.
2x^2+(-3+6)x-9
Apply the distributive property
2x^2(-3x+6x)-9
Remove the parentheses
2x^2-3x+6x-9
Factor out the greatest common factor from each group
Group the first two terms and the last two terms
(2x^2-3x) (6x-9)
Factor out the greatest common factor in each group.
x(2x-3)+3(2x-3)
Factor the polynomial by factoring out the greatest common factor, 2x-3
(x+3) (2x-3). So, the quotient is 2x-3
