Which line has an equation of y = negative 5 x + 4 in slope-intercept form? a line passing through the points (1, 9) and (3, 19)
a line passing through the points (2, –14) and (4, –24) a line passing through the points (1, 1) and (3, 11) a line passing through the points (2, –6) and (4, –16)
A) x + y = 7 B) 10y + x = 10x + y + 9 collecting terms of equation B B) -9x + 9y = 9 multiplying A) by 9 A) 9x + 9y = 63 then adding it to equation B) B) -9x + 9y = 9 18y = 72 y = 4 x = 3
