Question

Write an equation for the line shown on the right.The equation of the line is y =(Type an expression using x as the variable. Simplify your answer. Use integers or fractions for anynumbers in the expression.)

Answer 1

$\begin{gathered} y=mx+b \\ where \\ m=\text{slope} \\ b=y-\text{intercept} \end{gathered}$

Therefore,

(0, 4)(3, 8)

$m=\frac{8-4}{3-0}=\frac{4}{3}$$\begin{gathered} 4=\frac{4}{3}(0)+b \\ 4=b \\ \end{gathered}$$y=\frac{4}{3}x+4$
