Near the end of the "Slope" module there are 2 videos and one activity that use the slope-intercept equation before it is introduced:

Slope from equation

Converting to slope-intercept form

Exercise: Slope from equation

If you check the Q&A section for the two videos you will see that learners are completely confused by the sudden jump.

The idea of slope-intercept form is not introduced until the very next module "Intro to slope-intercept form"

My suggestion is to move the 2 videos and the exercise mentioned above into the "Intro to slope-intercept form" module.
