4y = 3x - 2      To find the y-intercept, let x = 0 and solve for y. 4y = -2 y = -1/2   (0,-1/2)   To find the x-intercept, let y = 0 and solve for x. 0 = 3x - 2 2 = 3x 2/3 = x     (2/3,0)  

Start with the Point-Slope Form since that is the information you are given. y - y1 = m(x - x1) y + 4 = 1(x + 1) y + 4 = x + 1 y = x - 3

Do you mean 45 minutes to paint one room? If so, it would take Carlos 45(7) minutes = 315 minutes 60 minutes = 1 hour 315 minutes(1 hour/60 minutes) = 5 1/4 hours to paint 7 rooms 45 minutes = 3/4 hours (3/4)(9)(13.50) = $91.13
