1) slope = (y2 - y1)/(x2-x1) = (4-(-1))/(3 -2)= 5/1 = 5
2) Slope-intercept from is
y = mx +b, where m is a slope and b is y-intercept.
m=5
3) y=5x + b
Take point (3,4), where y=4, x=3.
4=5*3 + b
4=15 + b
b= - 11
4) y=5x + b, and b = - 11, so
y=5x - 11.
y=5x - 11 is an equation in slope-intercept form.
