Answer:
Step-by-step explanation:
Notice that in the chart, the 2 grey sections (slope and y-intercept) are the two numbers that we need in order to write our equation.
(CHART #1)
We know the slope and a point (x,y). We can use this information to solve for b. Then we can write our equation.
First we will substitute the information that we know (that is in our chart) into the equation, y = mx + b. Then you will solve for b. (CHART #2)
Now we know the slope (m) is -2 because that was given to us. We also now know the y-intercept (b), which is 9 because we just solved for b.
We can now write our equation!
m = -2
b = 9
y = mx + b
y = -2x + 9
Answer:
.
Step-by-step explanation:
.
120° because 155-35=120 since IJZ is inside the IJK so you would have to subtract the ZJK from the IJZ.
Add three to both sides
2x greater than 14 - 5x
Add 5x to both sides
7x greater than 14
divide both sides by 7
x is greater than 2
