Need assitance on how to do the following problem on my TI-84 Plus
Graph and find the equation of the line from the given information
The line that passes through the points (-2,1) and (3,-2).
**
Equation for a line: y=mx+b, m=slope, b=y-intercept
slope=∆y/∆x=(-2-1)/(3-(-2))=-3/5
Equation: y=-3x/5+b
Solving for b using coordinates of one of the given points (-2,1)
1=(-3*-2)/5+b
b=1-6/5=-1/5
Equation: y=-3x/5-1/5
see graph below as a visual check:
You should get a similar graph on your TI-84 when you punch in the equation
