Answer:
Step-by-step explanation:
a) The y-coordinates of points A and B are both -2, so there is no change in the y-value between those points. The x-coordinates differ by 4, so the slope is ...
... slope = (change in y)/(change in x) = 0/4 = 0
b) The y-value is constant at -2 for any value of x, so the equation of the line is ...
... y = -2
Answer:
y=5x-3
Step-by-step explanation:
y=mx+b where m=slope and b= y-intercept
A goes in stock price decreased
B goes in stock price increased
C goes in stock price remained constant
D goes in stock price decreased
E goes is stock price increased

Answer:
Step-by-step explanation:
first we gotta find the slope of the first line
(-4,-3),(4,1)
slope = (y2 - y1) / (x2 - x1) = (1- (-3) / (4 - (-4) = (1 + 3) / (4 + 4) = 4/8 = 1/2
so the slope is 1/2.....so we are looking for a line that is perpendicular....perpendicular lines have negative reciprocal slopes...all that means is flip the slope and change the sign....so the slope we need is :
1/2....flip it....2/1.....change the sign....-2.....we need a -2 slope
y - y1 = m(x - x1)
slope = -2
(-4,3)...x1 = -4 and y1 = 3
now sub
y - 3 = -2(x - (-4) =
y - 3 = -2(x + 4) <=====
