Write the equation of the line that has a slope 4 and passes through the point (-1, 5) y - 5 = -4(x + 1)
y + 5 = -4(x + 1)
y - 5 = 4(x + 1)
y + 5 = 4(x - 1)

Acolony contains 1500 bacteria. the population increases at a rate of 115% each hour. if x represents the number of hours elapsed, which function represents the scenario? f(x) = 1500(1.15)" f(x) = 1500(115) f(x) = 1500(2.15) f(x) = 1500(215)

Is the point (0, 8) on the x-axis or y-axis? how do you know?

Astudent draws two parabolas both parabolas cross the x axis at (-4,0) and (6,0) the y intercept of the first parabolas is (0,-12). the y intercept of the second parabola is (0,-24) what is the positive difference between the a values for the two functions that describe the parabolas
