The slope of the graph of the equation y = 2 x minus 2 is 2. What is the y-intercept? y-intercept =

(0, -2)

Step-by-step explanation:

y= 2x - 2

To find the y-intercept, or where the graph hits the y-axis, you plug 0 in for x

y= 2(0) - 2

y= -2

because 2 times 0 is 0, then 0 - 2 is -2

If they ask for just the value, it is -2

If they ask for the coordinate, it is (0, -2)

the answer is -2

Step-by-step explanation:

answer: cos [   arcsin (3/5) - arccos (1/2) ] =

step-by-step explanation: × = 3/5 = 0.6--> x = 36.87 and x = 180 - 36.87 = 143.13 deg

cos y = 1/2 --> y = +- 60 deg a. cos (x - y) = cos (143.13 - 60) = cos 83,13  

=

0.12

b. cos (36.87 - 60) = cos (-23.23) = 0.92
