First you have find the slope (a) in order to find the value of the y intercept (b).
To compute the slope, you simply have to find the difference of y coordinates and divide them by the difference of x coordinates:
a = (y2-y1)/(x2-x1)
a = (7-3)/(-2–0)
a = 4/-2
a = -2
To compute the y intercept denoted by b, we substitute the value of a with -2 in the formula and choose any point (x,y) and substitute their values in the formula as well. Like so:
I choose point A:
3 = (-2)(0) + b
3 = b
Answer:
I can't see the whole question. If they want the area of the front it is 84
Step-by-step explanation:
Answer is 16:40
Add up the parts of the sweets so 2+5=7.
Then with the total amount (56)/7=8.
8x2= 16
8x5=40
Answer:
4(3n + 2)
Step-by-step explanation:
as we know perimeter of a square is 4 x side
one side is 3n + 2
4 sides = 4(3n +2)
