Question

A line with a slope of 5 passes through the point (1,9). What is its equation in slope-intercept form? Write your answer using integers, proper fractions, and improper fractions in simplest form.​

Answer 1

y = 5x + 4

Explanation:

The equation of a line in slope- intercept form is

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

Here m = 5, then

y = 5x + c ← is the partial equation

To find c substitute (1, 9) into the partial equation

9 = 5 + c ⇒ c = 9 - 5 = 4

y = 5x + 4 ← equation of line
