1. find the value of y so that the line passing through (6, y) and (7, 5) has a slope of -3.

2. write the equation of a line in point-slope form that has a slope of -1 and passes through the point (-2, 5).

3.write the equation of a line in slope-intercept form passing through (2, 7) and (-2, 9) y=1/3x+5 and passes through (-9, 5)

5. write the equation of a line in slope intercept form that is perpendicular to the line y = –4x and passes through the point (2, 6)

6. write the equation of a line in slope-intercept form that has a slope of and passes through the point (8, -1)

Daniel expanded the expression as shown below -2(-8x-4y+3/4)=-10x-8y-11/4 what errors did he make? check all that apply

52 cm radius = diameter = area = circumference = circumfer

In may you used 400 kilowatt-hours of energy for electricity. a. calculate the total electrical energy use in joules. b. calculate your average power use in watts. c. assume that your power supplier generates electricity by burning oil. note that 1 liter of oil releases 12 million joules of energy. how much oil is needed to generate the electricity you use? give your answer in both liters and gallons. a. the total electrical energy use was nothing _ joules. (type an integer or a decimal.) b. the average power use is nothing _ watts. (round to the nearest whole number as needed.) c. to generate the electricity you used, nothing _ l is needed. (round to the nearest whole number as needed.) to generate the electricity you used, nothing _ gal is needed. (round to two decimal places as needed.)
