Question

Which is the equation of a line that has a slope of 1 and passes through point (5, 3)?

y=x-2
y = x + 2
y = x + 3
y = x-5

Answer 1

Plug the x (5) and the y (3) into the x and y and solve 3=3.... so y= x-2 :)

Answer 2

y=x-2

Explanation:

slope intercept form

• y= mx+b

Slope =1

• m=1 ⇒ y=x+b

point (5, 3), finding the intercept

• 3=5+b ⇒ b=-2

the equation:

• y=x-2
