Question

graph each line and write the equation of line in the slope-intercept form : passes through the point (2,-4) with y intercept (0,-2)

Answer 1

Answer: f(x) = -1 x - 2

Explanation:

y=mx+b

-replace the x and y with the coordinates of the y-intercept and solve for b.

-2 = m(0)+b

-2 = b

y = mx + (-2)

- replace the x and y with the other given point and solve for m.

-4 = m(2) - 2

m = - 1

Equation of the line : y = -1 x -2
