Step-by-step explanation:
the typical line equation is
y = ax + b
a is the slope. it is the ratio of "y coordinate change / x coordinate change".
b is the y-intercept (the y value when x = 0) indicating the point, where the line crosses the y-axis.
going from one to the other point
x changes by +8 (from -6 to 2).
y changes by +4 (from 3 to 7).
so, the slope a is +4/+8 = 1/2.
the semi-finished equation is
y = 1/2 x + b
for b we use one of the points in the equation and since for b. let's go for (2, 7) :
7 = 1/2 × 2 + b = 1 + b
6 = b
so, the full equation is
y = 1/2 x + 6
I think the answer is 36%
252 divided by 9 is 28
Firstly, I muplity 20 and 9.
I have 180.
Then I also muplity 8 and 9.
I got 72.
Then I add 72 and 180 which got me 252.
(I hope this helped!)
He has seven models because 21 divided by 3 is seven
Answer:
1. The ratio in the table above is a 2.5 : 1 ratio.
2. The second row represents that if you use 15 cups of flour you need 6 tablespoons of flour. (I’m not 100% sure this one is right)
3. 10 cups of flour and 4 tablespoons vanilla
Step-by-step explanation:
3. If you divide your number of flour by 2.5 you get the amount of vanilla you must use
