Question

write an equation in slope-intercept form of the line through point P(6,7) with slope-2.
Will medal for help, Guess is D

Answer 1

y = -2x + b

7 = -2(6) + b

b = ?

Answer 2

this isnt the same question?

Answer 3

slope-intercept form is y=mx+b

they tell you the slope, m, is -2, so you plug that into your equation

x and y will change, so what you need to find is b

plug in the x and y values they give you, then solve for b

7=-2(6)+b

7=-12+b

add twelve to both sides

19=b

change x and y back to variables and add in the value of b you found

y=-2x+19

Answer 4

oh i see, that helps a lot more thank you
