Question

Fill in the missing numbers to complete the linear equation that gives the rules for this tablex: 4, 5, 6, 7y: 56, 70, 84, 98y = ?x + ?

Answer 1

the two points are

A(4,56) and B(5,70)

so, the linear equation is

$y-70=\frac{70-56}{5-4}(x-5)$$\begin{gathered} y-70=\frac{14}{1}(x-5)_{} \\ y-70=14x-70 \end{gathered}$$y=14x$

thus, the equation is

y = 14x + 0

so we can put 14 in first place and 0 in second
