Explanation:

Gradient of line = \(\frac{\text{Change in y}}{\text{Change in x}}\) = \(\frac{y_2 - Y}{x_2 - x}\)

y\(_2\) = 0\(_1\)

Y\(_1\) = 4

x\(_2\) = 3 and x\(_1\) = 0

\(\frac{y_2 - y_1}{x_2 - x_1} = \frac{0 - 4}{3 - 0} = \frac{-4}{3}\)
quation of straight line y = mx + c

Where m = gradient and c = y

intercept = 4

y = 4x + \(\frac{4}{3}\) multiply through y

3y = 4x + 23
