Question

Write an equation of a line whose slope is 10 and y-intercept is (0,-20).

Answer 1

Explanation:

y = mx + b

Main components:

m - slope

b - y-intercept

Those two components are already given:

Slope = 10

y - intercept = -20

y = 10x - 20

There are at least three equations:

y intercept form -

y = 10x - 20

standard form -

-10x + y = -20

point slope -

y -(-20) = 10 (x - 0)

y + 20 = 10x
