Answer:
A is the answer
Step-by-step explanation:
To understand problems like these, we must understand how Slope Intercept Form (SIF) works, and how to solve an equation.
<span>A
</span>SIF is "y=mx+b" where "m" is the slope and "b" is the y-intercept.
y='m'x+''b''
y='3'x-''4''
We can see that in this equation, the slope is 3/1 or 3, and the y-intercept is -4.
<u>B
</u>For this one, we must solve for "y," and then proceed with the same thing we did in Part A.
4x-5y=15
-4x -4x
-5y=-4x+15
/-5 /-5
y='4/5'x-"3"
Using the math above, we can see that the slope is 4/5, and the y-intercept is -3.
Answer: 517
Step-by-step explanation:
Answer:
3/5
Step-by-step explanation:
Set it equal to 0
5x-3=0
Then solve for x
5x=3
x=3/5
Check
5(3/5) - 3
3-3
0
