Answer:
Point-Slope: 
Slope-Intercept: 
Step-by-step explanation:
The point-slope formula is
. The slope-intercept formula is
. Since we are given the point and slope, we can directly plug it into the point-slope formula.
Point-Slope


To find the slope-intercept form, we can manipulate the point-slope form to get the slope-intercept form.
Slope-Intercept


Step-by-step explanation:
try adding them together that'll make sense duh lol
