1. Which equation is equivalent to y – 6 = –12(x + 4)? (1 point)y = –6x – 48 y = 6x – 48 y = –12x – 42 y = –12x – 54 2. Which point is located on the line represented by the equation y + 4 = –5(x – 3)? (1 point)(–4, –5) (–5, –4) (3, –4) (–3, 4) 3. Which equation represents the line that passes through the points (6, –3) and (–4, –9)? (1 point)y + 4 = (x + 9) y + 4 = (x + 9) y - 3 = (x + 6) y + 3 = (x – 6) 4. The population of a city increases by 4,000 people each year. In 2025, the population is projected to be 450,000 people. What is an equation that gives the ci

    1. y - 6 = -12(x+4) y - 6 = -12x - 48 y - 6 + 6 = -12x - 48 + 6 y = -12x - 42 2. y + 4 = –5(x – 3) y + 4 = -5x + 15 y + 4 - 4 = -5x + 15 - 4 y = -5x + 11 now plug in points y=-4 x=-5 -4 = -5(-5) + 11 -4 = 25 + 11 -4 ≠ 36 y=-5 x=-4 -5 = -5(-4) + 11 -5 = 20 + 11 -5 ≠ 31 y=-4 x=3 -4 = -5(3) + 11 -4 = -15 +11 -4 = -4 <-- This one is correct so this is the answer. 3. first find the slope. slope (m) = {y_2 – y_1}/{x_2 – x_1} y_2 = -3 x_2 = 6 y_1 = -9 x_1 = -4 m = {-3 – (-9)}/{6 – (-4)} m = {-3 + 9}/{6 + 4} m = 6/10 now reduce m = 3/5 put the equations in slope-intercept form and find the one with the matching slope. 4. I don't know #4 sorry.
