Question

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

Answer 1

y=-3x + 5

Explanation:

Graph the point and draw the slope line to see where the line will hit on the y-axis.

Answer 2

y= -3x + 5

Explanation:

y-y1=m(x-x1)

m= slope = -3

(2,-1) = (x1, y1)

plug in the values

y+1= -3 (x-2)

y= -3x+6 -1

y= -3x + 5
