Answer:
f(x) = 3x +5
Step-by-step explanation:
The x-values change by 1 from the first line to the second.
The y-values change by -13-(-16) = 3 from the first line to the second.
Then the "rate of change" is ∆y/∆x = 3/1 = 3. This will be the coefficient of x in the equation. The last choice is appropriate:
f(x) = 3x + 5
Answer:-5,-4,-3,-2,-1,-0,1,2,3,4
Step-by-step explanation:
Pythagorean theorem: a^2 + b^2 = c^2
The hypotenuse is always the c in the equation.
If the two side lengths they gave you are not the hypotenuse, then enter
4.5^2 + 5.6^2 in the calculator, then find the square root of that. :-)
Answer:
A
Step-by-step explanation:
slope of the given line: -a/b
-4/-2 = 2
realtionship between the slopes of two perpendicular lines:
m = -1/m
slope of the second line
-1/2
line
y-y1 = m(x-x1)
y - 6 = -1/2(x-4)
y = -1/2x + 2 + 6
y = -1/2x +8
