Answer:
y = 
Step-by-step explanation:
The equation used to find the equation for a line with two intercepts is called point slope form. 
, where 
and 
are the intercept points and m is the slope.
However, we need the slope to use this formula.
Use 
m = \frac{y_{1} - y_{2} }{x_{1} - x_{2}}
y - ( -7 ) = m ( x - ( 4 ) )
y - ( -7 ) = -7/4 ( x - ( 4 ) )
y + 7 = -7/4 ( x + 4 )
y + 7 = 
y + 7 = 
y + 7 = 
y + 7 = - 7
y =

Answer:
It is a solution
Step-by-step explanation:
y = -4x - 8
Let x = -9 and y = 28
Substitute these values in
28 = -4(-9) -8
28 = 36 -8
28 =28
This is true so it is a solution
Answer:
It is a equation
Step-by-step explanation:
Because it has an equal sign if it does not it will be a expression.
Answer:
b) -10
Step-by-step explanation:
x^2 + 3x + k = (x - 2)(x - a)
(x - 2)(x - a) = x^2 - 2x - ax + 2a = x^2 + [-2 - a)x] + 2a
-2 - a = 3
2a = k
a = -5
k = 2(-5) = -10
Answer: b) -10
