A. slope intercept form is y=mx+b where m is your slope and b is your y-intercept. Since it gives you the slope (4) and the y-intercept (-9) all you have to do is plug it into the equation to get y=4x-9
b. This one is a little bit trickier but by no means impossible. the first thing we want to do is find the slope, and in order to do this we take the second y minus the first and divide it by the difference of the second x and the first x. the way that would look in this case is (10-6)/(4-0) and when we simplify this we get 4/4=1
Since our slope is 1, we just need to find the value of y when x=0, In this problem it is given to us with the point (0,6) if we plug both of this into our equation we get y=x+6 (the 1 in front of the x is optional

not really sure so yeah B
Answer:
15
Step-by-step explanation:
The statement indicates that Daniel scored 3 points which represents 20% of his average points and from this information, you can use the rule of three to find his average point total which is the 100%:
3 points → 20%
x ← 100%
x= (3*100)/20
x= 15
Daniel's average point total is 15.
Answer:
6.15 × 10⁵
Step-by-step explanation:
When converting a number of scientific notation, we need to move the decimal point until the number is greater than 1 and less than 10, then multiply this by 10 to the power of the number of places we moved the decimal point (negative when moving it forwards, positive when moving it backwards).
Therefore, 615000 = 6.15 × 10⁵
Answer: x = 9
Step-by-step explanation:
x can be equal to 9.
Lets plug in 9 to the variable x, in this equation, x -3 = 6.
x - 3 = 6
9 - 3 = 6 (plugged in 9 for x)
So, x = 9.
