The formula for slope is (y2 - y1)/ (x2 - x1)
Let's use (2,6) and (4,12)
12 - 6 = 6
4 - 2 = 2
6/2 = 3
The slope is 3.
Answer: slope = 21, y-int = 15
Step-by-step explanation:
f(x) = -7x + 9
g(x) = -7(x + 2) + 9 = -7x - 5
h(x) = -3(-7x - 5) = 21x + 15
slope = 21
y-intercept = 15

Answer:
Step-by-step explanation:
In similar triangles corresponding triangles are in same ratio.
![\frac{15}{5}=\frac{12}{y}](https://tex.z-dn.net/?f=%5Cfrac%7B15%7D%7B5%7D%3D%5Cfrac%7B12%7D%7By%7D)
Cross multiply,
15 * y = 12 * 5
y = ![\frac{12*5}{15}](https://tex.z-dn.net/?f=%5Cfrac%7B12%2A5%7D%7B15%7D)
y = 4
Answer: x=3, y=2.
Step-by-step explanation:
y = - x + 4
y = x − 2
- x + 4 = x − 2
-x-x=-2-4
-2x=-6
x=(-6):(-2)=3
y=x-2=3-2=1
x=3, y=2.
