Answer:
(-1)*(-1)=1
1*(-1)= -1
first option (-1) is the right answer.
In short, the average rate of change is plainly the slope of the set, so we can pick any two points off there, say 2, 35 and 10, 115,
Reflection is when the pre-image is flipped over a line.
Answer:
sorry to say this but if you write the question in english it would be easy to understand
Step-by-step explanation:
Answer:
y= 3.5x+22.5
Step-by-step explanation:
The standard equation of a line a expressed as y = MX+c
m is the slope
c is the y-intecept
Get the slope
m = y2-y1/x2-x1
m = -9-5/-9+5
m = -14/-4
m = 7/2
Get the y- intercept
Substitute any of the point say (-5,5) and m = 7/2 into the equation y = MX+c
5 = 7/2(-5)+c
5= -35/2+c
5 =-17.5+c
c = 5+17.5
c =22.5
Get the required equation
Recall that y = MX+c
y= 3.5x+22.5
