Question

What is the equation of the line that passes through the point (1,4) and has a slope of 4

Answer 1

y = 4x

Explanation:

Equation of line in point -y intercept form:

`\sf \boxed{\bf y-y_1=m(x- x_1)}`

`\sf x_1 = 1 \ ; \ y_1=4 \ \& \ m = 4`

y - 4 = 4(x -1)

y - 4 = 4*x - 4*1

y - 4 = 4x - 4

Add 4 to both sides

y = 4x - 4 + 4

y =4x
