The line with x-intercept of 10 and y-<br> intercept of -2.
Yuri [45]

Answer:

y = \frac{1}{5} x - 2

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Calculate m using the slope formula

m = \frac{y_{2}-y_{1}  }{x_{2}-x_{1}  }

with (x₁, y₁ = x- intercept (10, 0) and (x₂, y₂ ) = y- intercept (0, - 2)

m = \frac{-2-0}{0-10} = \frac{-2}{-10} = \frac{1}{5}

The y- intercept c = - 2

y = \frac{1}{5} x - 2 ← equation of line
