Question

Write the equations of each line in slope-intercept form. (y=mx+b) Each of these are worth 2 points.

Answer 1

first one: y = 5x+5

second: y = -4x -4

Explanation:

to find slope intercept, you need 2 things:

Slope

Y intercept

Slope is rise/run (as taught in elementary school) and the y intercept is the place where the line intersects the Y axis

To find the Y axis, replace X with 0

Y = (slope)x + (y intercept)

Y = (5-0)/(0-(-1))x + (y intercept)

Y = 5x + (y intercept)

If you look at the graph, at X = 0, Y= 5

Therefore, Y=5x+5
