Question

Can someone please help with this problem?
Find the equation of a line given the point and slope below. Arrange your answer in the form y = mx + b, where b is the constant.

(1, 3)
m = 3

Answer 1

y = mx + b
slope(m) = 3
(1,3) x = 1 and y = 3
now we sub....
3 = 3(1) + b
3 = 3 + b
3 - 3 = b
0 = b

so we have : y = 3x + 0

or this way...
y - y1 = m(x - x1)
slope(m) = 3
(1,3) x1 = 1 and y1 = 3
sub
y - 3 = 3(x - 1)
y - 3 = 3x - 3
y = 3x - 3 + 3
y = 3x + 0

Thank you so much!!
