Answer:
The y-intercept is -2
Step-by-step explanation:
Based on the equation y + 2 = 0 (y = -2), you can eliminate all answers except for the second one. This is because, the y is the horizontal line, while the x is the vertical line. The value of x does not always equal the value of y, only sometimes. Finally, the slope of y = -2 is 0, not undefined. However, the slope of x = -2 is undefined.

The answer would be .03. How I solved the problem is I moved the decimal of .21 two places to the right resulting in 3. Then I moved the decimal back after getting the answer resulting in .03
Answer:
m<1 = 51
m<2 = 34
m<3 = 95
m<4 = 38
m<5 = 47
m<6 = 74
m<7 = 59
Step-by-step explanation: because to get angle 1 you take 180 (because its is a straight line) and subtract the angle 129 giving you m<1 witch is 51. the second one is 180 - (m<1 + 95) =m<2 witch is 34 so m<2 = 34. third is the angle 95 because the lines that intersect give equal opposite angles so m<3 = 95. Four is 180 - (m<3 + 47) =m<4 witch is 38. fifth is opposite angle so it is 47. sixth is m<5 +m<6 + m<7 = 180 so m<5 is 47 and we can find m>7 by subtracting from 180 the angle 121 giving us m<7 = 59 so we will add m<5 and m<7 and subtract from 180 giving us m<6 witch is 74.
