1. insert points (17,9) and (5,29) into y = mx + b 29 = 5m + b 9 = 17m + b 2. Isolate b in each equation: b = 29  5m b = 9  17m 3. Set b = b 29  5m = 9  17m 4. Use inverse operations to place like terms on the same side: 29  9 = 5m  17m 20 = 12m 5. Isolate m: 20/12 = m 3/5 = m 6. Find b by inserting m into one of the equations in step 2: b = 29  5(3/5) b = 29 + 3 b = 32 7. Insert the values of m and b into y = mx + b: y = (3/5)x + 32 8. You're done

just use \[m=\frac{ Y _{2}Y _{1} }{ X _{2}X _{1} }=\frac{ 299 }{ 517 }=\frac{ 20 }{ 12 }=\frac{ 5 }{ 3 }\]
