Question

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

to find b (y intercept):

y=mx+b
3=3(1) +b this is from (y=3 from the set 1,3)=(m=3)(x=1 from the set 1,3)
3=3+b
3-3=b
b=0

The equation for the line in the form y = mx + b is:

y=3x+0


to check
y=3x+b
3=3(1)+0
3=3 it is correct
