Find the slope using \(\frac{y2 - y1}{x2-x1}\)
\(\frac{3-(1)}{0-3}\) = \(\frac{-4}{3}\)
The y intercept (i.e. the value of y when x = 0) is 3
Going through the answer choice, the equation with slope of -4/3 and y intercept of 3 is Answer choice (D) y=−4/3 (x)+3
\(\frac{3-(1)}{0-3}\) = \(\frac{-4}{3}\)
