Question

Write the equation of the line thay passes through the point (2,-1) and has a slope of -3​

Answer 1

Explanation:

use the point slope equation.

y-y1 = m(x-x1)

the point is (x1, y1) = (2, -1)

the slope is m = -3

y+1 = -3( x-2)

y = -3x +6-1

y = -3x +5

Answer 2

Y = -3x -1

Explanation:

Y = mx + b

Y is the y intercept (x,y) always graph on y axis

M is the slope
