Question

Write the equation of the line that passes through (3, –2) and has a slope of 4 in point-slope form.
y + 2 = 4(x – 3)
y – 3 = 4(x + 2)
x – 3 = 4(y + 2)
x + 2 = 4(y – 3)

Answer 1

OK - this is just a case of putting numbers into the formula

It tells you the slope is 4 and the point (x1,y1) is (3,-2)

the equation is
y -y1 = m(x-x1)

just put the numbers in

(hint: be careful of the minus signs....)

Answer 2

btw :

m is the slope (=4 in this case)

Answer 3

So 3 - (-2) = 5?

Answer 4

look at the format of teh answers - they have x and y in them

the answer looks EXACTLY like this:
y -y1 = m(x-x1)

but you need to put in the values for y1, m and x1

so write the equation in that form using the point and slope you were given in the question

Answer 5

Oh okay, So would it be, y+2=4(x-3) ?

Answer 6

Yes - well done

Answer 7

Thank you!
