You can put this solution on YOUR website! how do i do answer the question "write an equation of a line that passes through the point (1,6) and has a slope of -3
:
Use the point slope formula: y - y1 = m(x - x1)
in the problem
x1=1, y1=6, m=-3
so you have
y - 6 = -3(x - 1)
y - 6 = -3x + 3
y = -3x + 3 + 6
y = -3x + 9, is the equation for the line
;
:
You can prove to yourself that this is the equation, replace x with 1 and find y
