Question

Write the equation of the line that has a slope of 1 and goes through the point (2, 3). Hint: Use y = mx+b

Answer 1

y = x + 1

Explanation:

the equation of a line in slope- intercept form is

y = mx + b ( m is the slope and b the y- intercept )

here m = 1 , then

y = x + c ← is the partial equation

to find c substitute (2, 3 ) into the partial equation

3 = 2 + c ⇒ c = 3 - 2 = 1

y = x + 1 ← equation of line
