Write an equation in slope intercept form (-5,19) and (5,13) i got undefined but big ideas math won't let me type that how to i
1 answer:
The slope-intercept form is
How you submit that in your onlie env. you have to figure out using the help of that system.
Take the general slope intercept form y = mx + b and fill in both coordinates:
19 = -5m + b
13 = 5m + b
If you add them, you get a new equation with only b:
32 = 2b, so b = 16
Next, you find m, for instance by putting b back into the 2nd formula:
13 = 5m + 16
-3 = 5m
m = -3/5
Now you have found b and m to have the slope-intercept form:
