Answer:
-4
Step-by-step explanation:
Slope can be found with 
Pick two points on the graph that the line runs through
(-2, 4) will fill the values of x1 and y1, and (-1, 0) will fill the values of x2 and y2
Insert the coordinates into the formula



Therefore the slope is -4
S = p/(q +p -pq)
q +p -pq = p/s
q -pq = p/s - p
q(1-p) = p/s - p
q = (p/s - p) / (1-p)
An equation between two variables that gives a straight line when plotted on a graph.
2y = x+ x+ 1
2y = 2x + 1
y = (2x+ 1) /2
y = x + 1/2
According to the graph, this equation is linear
Answer:
16
Step-by-step explanation:
Given
x² + 8x = 4
To complete the square
add ( half the coefficient of the x- term )² to both sides
x² + 2(4)x + 16 = 4 + 16, thus
(x + 4)² = 20 ← equivalent equation
