Question

Write the equation y-2=1/4(x-4) in the most appropriate for identifying the slope and y-intercept of the function. What are the slope and y-intercept?

Answer 1

y = mx + b y = 1/4x + 1

m = 1/4

b = 1

Explanation:

first you should distribute

y - 2 = 1/4(x - 4)

y - 2 = 1/4x - 1

and then isolate y by adding 2 to both sides of the equal sign to cancel out the negative 2 on the left

y - 2 = 1/4x - 1

+2 +2

y = 1/4x + 1

the slope (m) = 1/4

the y-intercept (b) = 1
