Question

Find the equation to the line below.
y=4/5x +?

Answer 1

Answer:

y =x - 1

Step-by-step explanation:

Slope intercept of a line: y =mx + b

Here, m is the slope and b is the y-intercept.

Plot any two points on the line. (5,4)  & (0,-1)

$\sf \boxed{Slope =\dfrac{y_2-y_2}{x_2-x_1}}$

          $\sf =\dfrac{-1-4}{0-5}\\\\=\dfrac{-5}{-5}\\\\=1$

m = 1

At y-intercept x = 0.  So, the -1 is the y-intercept.

m = 1 & b = -1

y = 1x + (-1)
