An equation that goes through (-2, 1) and has a slope of 4 is y = 4x + 9.
You can find this by looking for the y-intercept (b) by using the slope (m), the point and slope intercept form. The work is below for you.
y = mx + b
1 = 4(-2) + b
1 = -8 + b
9 = b
Now we can use that and the slope to create the equation y = 4x + 9
The measure of ∠BEC would be 80 degrees
Answer:

Step-by-step explanation:
Given the equation
,
By the quadratic formula,
,

We have two different solutions for x where
and 
So, x =
and 
Therefore, the solutions to this quadratic equation is x = -8, -1, by the quadratic formula.
If C = infinity and B = infinity, then:
C = B
C + B = infinity
C - B = 0
CB = infinity ............ ( C multiplied by B )
however, C divided by B is undefined.
