Question 1169649: Question 1: The amount of medication M (in milligrams) in a patient’s body gradually decreases over time t (in hours) according to the equation M=1200-15t.
After 73 hours, how many milligrams of medication are left in the body?
Question 2: A staircase is to be built so that its maximum steepness is 0.4. If each step goes in 29 centimetres, what is the maximum height in centimetres it can rise vertically?
Question 3: A line passing through the points (5,-2) and (-1,t) has a slope equal to 3.
Question 4: What is the slope of any line parallel to the x-axis?
Question 5: Find the equation of the line through (2,7) that is parallel to the y-axis.
Question 6: Write down the equation of the line in slope-intercept form, given that its slope is -5 and it's y-intercept it 3
Question 7: Write the equation of a line which has slope 2/3 and goes through the point (0,-2)
Question 8: Find the equation of a line that has the same slope as y=9-10x and the same y-intercept as y=-3x-5
Question 9: A line L is perpendicular to the interval joining B (3,9) and C (-1,8)
Question 10: Use the two point formula to derive the equation of the line that passes through the points A (-10,2) and B (10,-14). Give your answer in general form.
