Determining a Linear Equation to Find an Input Value
Consider f(x) = 1.8x - 10 and g(x)
Select the equation that can be used to find the input
value at which f(x) = g(x), and then use that equation
to find the input, or x-value
f(x)
g(x)
-17.2
1.8x - 10 = -4; x = 10
0 18x = -4; x = - 20
-13.6
0 1.8x + 10 = -4 * = - 10
-6.4
