Answer:
slope(m) = y2 -y1/ x2 - x1
m = -1 - 2/ 2 - 1
m = -3/1 ; m = -3
using the formula y -y1 = m(x - x1)
y - 2 = -3( x -1)
y -2 = -3x +3
collect like terms
3 +2 = y + 3x
y + 3x = 5
y = -3x + 5( y = mx + c)
equation of the line= y = -3x + 5
Answer:
If a is positive, the parabola will open to the right, so the answer is C
Step-by-step explanation:
The answer is D because when you put the missing value which is x you replace it to 10 and then you solve it I hope this helps
Answer:
60
Step-by-step explanation:
4/3 = x/45
45/3=15
15*4=60
x=60
80. there's no mathematical equations, also there's nothing to compare
