Question

Slope Is --3, and (1, 2) is on the line.
The equation of the line is y

Answer 1

y= -3x + 5

Explanation:

Use the equation of a line formula:

y- y1 = m(x - x1)

where y1 and x1 are the y and x coordinates from the given point (1,2)

So y1= 2

x1= 1

And where m is the slope, -3

Plug in to get y-2 = -3(x-1)

Simplify and solve for y

y= -3(x-1)+2

y= -3x +3 +2

y = -3x + 5
