Are you sure you meant -3 to be the x-intercept? If so...
slope 2/3 and x intercept -3
How would you find y=ax+b?
a=slope=2/3 (x,0)=x-intercept=(-3,0).
First find b by plugging your values in:
0=%282%2F3%29%28-3%29%2Bb
0=-6%2F3%2Bb
0=-2%2Bb
2=2-2%2Bb
2=b
: Plug a=2/3 and b=2 into your equation.
y=%282%2F3%29x%2B2
Happy Calculating!!!
