Slope = -2, passing through (-4.0)
Type the point-slope form of the line.

Solve this system of equations. 12x − 18y = 27 4x − 6y = 10

15 and 14.7 are 1 apart, so 15 – 14.7 must be 1.

Grace is standing 18 feet from a lighthouse and kelly is standing 10 feet from grace. the angle that grace looks up to see the top of the lighthouse is 45°. the angle that kelly looks up to see the top of the lighthouse is y°. find the height, h, of the lighthouse. find the angle, rounded to the nearest tenth of a degree, in which kelly looks up to the top of the lighthouse. to the nearest tenth of a degree, find the value of x° . in two or more sentences, explain your calculations
