Answer:
<em>y = - 4x + 5 </em>
Step-by-step explanation:
y = mx + b
(0, b) y-intercept
m = 
~~~~~~~~~~
( - 2, 13)
(0, <em>5</em>) <----- y-intercept
(3, - 7)
(4, - 11)
<em>m =</em> 
= <em>- 4</em>
<em>y = - 4x + 5</em>
Answer:
z=3
Step-by-step explanation:
Add 3z and 2z
5z-5=25-5z
Add 5z on both sides to eliminate the -5z on the RHS
10z-5=25
Add 5 on both sides to eliminate the -5 on the LHS
10z=30
Divide by 10
z=3
Hope this helps!
10 800 0 to the first problem
5/8=10×w this is my equation then i divide by 10 on both sides
w=6.25
We'll use the slope-intercept form y = mx + b. Where m is the slope and b is the y-intercept.
We know the slope, -1/5. Now the equation looks like y = (-1/5)m + b
To find the y-intercept, plug in the ordered pair that the question gave us into our equation and solve for b.
7 = (-1/5)(-3) + b
7 = 0.6 + b
6.4 = b
b = 6 2/5
So, the y-intercept will be at 6 2/5.
