The slope-intercept form:

m - slope
b - y-intercept
The formula of a slope:

We have the points (-3, 1) and (2, -4). Substitute:

Therefore we have the equation of a line

Put the coordinates of the point (-3, 1) to the equation:

 <em>subtract 3 from both sides</em>
      <em>subtract 3 from both sides</em>

<h3>Answer: y = -x - 2</h3>
 
        
             
        
        
        
2 and the 4 needs to add subtract too much
        
             
        
        
        
Answer:
a. x = -9 or x = -2
b. -5(x - 4)
c. x = -3 or x = 5
d. x = ±7
Step-by-step explanation:
a. First person;
y = x² + 11x + 18
y = x² + 9x + 2x + 18
y = x(x + 9) + 2(x + 9)
y = (x + 9)(x + 2)
y = x = -9 or x = -2
b. Second person;
y = -5x + 20
The common factor is 5.
y = -5(x - 4)
c. Third person;
y = x² - 2x - 15
y = x² - 5x + 3x - 15
y = x(x - 5) + 3(x - 5)
y = (x + 3)(x - 5)
y = x = -3 or x = 5
d. Fourth person;
y = x² - 49
Applying the difference of squares formula;
(a² - b²) = (a - b)(a + b)
y = x² - 49 = x² - 7² = (x - 7)(x + 7)
y = (x - 7)(x + 7)
y = x = ±7

Answer: x = 0.75
Step-by-step explanation:
3x+x - 3 =0
4x - 3=0
4x = 3
x = 0.75
