Question

Enter the equation of the line in slope-intercept form.

Slope is 4, and (2, 5) is on the line.

The equation of the line is y = ?

Answer 1

Slope Intercept Form: y = mx + b

m = slope
b = y intercept

x₁ = 2
y₁ = 5

Point Slope Form: y - y₁ = m(x - x₁)

y - 5 = 4(x - 2)
y - 5 = 4x - 8
+ 5 + 5
---------------------
y = 4x - 3

Answer 2

y-5/x-2=4
y-5=4x-8
y=4x-8+5
y=4x-3
