• triangle a b c is shown with its exterior angles. angle b a c is (p + 4) degrees and angle a c b is 84 degrees. exterior angle x b c is (3 p minus 6 degrees). what is the measure of ∠xbc? m∠xbc = m∠bac + m∠bca 3p – 6 = p + 4 + 84 3p – 6 = p + 88 2p – 6 = 88 2p = 94 m∠xbc = °
  
• leon correctly found the slope and y-intercept of the line that passes through the points (9, –8) and (3, 4) as follows. m = startfraction negative 8 minus 4 over 9 minus 3 endfraction = startfraction negative 12 over 6 endfraction = negative 2. y = negative 2 x + b. negative 8 = negative 2 (9) + b. negative 8 = negative 18 + b. 10 = b. what is the equation of the line in slope-intercept form? y = negative 2 x + 10 y = 2 x + 10 y = 10 x minus 2 y = 10 x + 2
