Answer:
1
Step-by-step explanation:
the equation for a slope-intercept line is y=mx+b. In this equation, b represents the y intercept. In the equation you posted, 1 is in the place of b, so one is the y intercept.
hope this helps
Answer:
The last one
.
Step-by-step explanation:
1) There are three trigonometric ratios for right-angled triangles.

In a right triangle, the hypotenuse, h, is the side opposite the right angle. Relative to the acute angle θ, check the attachment, the legs are called the opposite side, o, and the adjacent side a.
2) In this case, we are given a length and an angle to find x and y.
Let's find x first. To find x we need to use
.

Find y.
Notice that, we can use the Pythagorean Theorem
to find y.


3) Round them off to the nearest tenth.


Therefore, the correct choice is the last one
.
Possible Answers:
1. b = 1.5
2. b = 20
3. b = 4
STEP-BY-STEP:
1. -12 ÷ -8
2. b + 20 = 8
3. b + -12 = -8

Please mark me as brainliest.
This took about 10 minutes to figure out, and write the equations, because I had to re-figure out how I got the original answers.

i think it may be wrong but im pretty sure that should be right.
