Question

Write the equation of the line that passes through (2,4) aunt has a slope of -1 in point slope form

Answer 1

The point-slope equation:

y - y1 = m(x - x1)

for a line that passes through point (x1, y1) and has slope m.

Use x1 = 2; y1 = 4; m = -1 in the equation above.

y - 4 = -1(x - 2)

Answer: y - 4 = -(x - 2)

Answer 2

y=mx+b is equation of a line

m= slope which is -1

b= y intercept which is 4

so, it would be y=  -x+4
