Question

What is the y-intercept?

Answer 1

Answer:

y = 2x - 3

Step-by-step explanation:

To solve for y, use the point slope formula: y2 - y1 / x2 - x1

Given the points (3, 3) and (4, 5) 5 - 3/4 - 3

2/1

m = 2

Use the slope m = 2 and one of the given points such as

(3,3) to substitute for x1 and y1 in the point-slope form

So, y - y1 = m x (x - x1)

y - (3) = 2 x (x-3)

Solve for to get the equation. y = 2x - 3
