Slope -3 1,4 on the line

Answer 1

Start with point-slope form

y - 4 = -3(x - 1)

Answer 2

Equation of a line:

y = mx + b

where m is the slope and b is the y-intercept. m = -3, so:

y = -3x + b

To find the value of b, plug in the x and y values, (1,4):

y = -3x + b

4 = -3(1) + b

Solve for b.
