Question

Find the equation of a line that passes through the point (3,4) and has a gradient of 5. Leave your answer in the form y = mx + c​

Answer 1

Answer:

y = 5x - 11

Step-by-step explanation:

The equation of a line in slope- intercept form is

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

Here m = 5 , then

y = 5x + c ← is the partial equation

To find c substitute (3, 4) into the partial equation

4 = 15 + c ⇒ c = 4 - 15 = - 11

y = 5x - 11 ← equation of line
