Answer:
a. -2
b. s = 2 and y = -5
c. (2.5, -9)
d. -7x - 2
Step-by-step explanation:
a. In the image, I have used rise over run, which is -8/4 or -2.
b. slope formula is mx + b = y, where m is slope and b is the y-intercept. In the equation 2x - 5y = -10, 2 is the slope and -5 is the y-intercept.
c. Plug in all given numbers into an equation and the ones you do not have will be in the points you need it to be. Once you graph the equation you will receive (2.5, -9).
d. y = mx + b
5 = (-7)(-1) + b
5 = 7 + b
-2 = b
y = -7x - 2
To round to the nearest tenth place you are going to round the last two digits of that, you should get 519.7
Answer:21.2
do x/45 = 24/51 cross multiply and get 51x=1080 simplify and get 21.2

The same as of sec 20 degrees in radians to obtain 20 degrees in radian multiply 20° by / 180° = 1/9
