Answer:
y =-2x+7
Step-by-step explanation:
Hello : let A(2,3) B(1,5)
the slope is : (YB - YA)/(XB -XA)
(5-3)/(1-2) = 2/-1 =-2
an equation is : y=ax+b a is a slope
y = -2x +b
the line through point (2,3) : 3 = (-2)(2)+b
b = 7
the equation is : y =-2x+7
Answer:
y=-10
Step-by-step explanation:
y=-2(3)-4
y=-10
Answer:
Step-by-step explanation:
The denominator of the fractional exponent is the index of the root.
F(x)=-3.25x +22.41
f(-4.2)= 3.25(-4.2)+22.41 = 8.76
