Answer:
y= -4x+1
Step-by-step explanation:
If you want to write this equation in slope intercept form, you need to find the y-intercept. Here is your current equation y= -4x + b. Then, substitute the x and y for the coordinate. Now, it should look like this: 9= -4(-2) + b. Multiply -4 and -2 to get 8. Now, this is your equation: 9= 8 + b. Then, subtract 8 from both sides to get your final answer, 1=b. Now that you have your y-intercept, go back to your original equation and fill in 1 for b. This is your final equation: y= -4x+1. Hope this helped!

Answer:WX=65
Step-by-step explanation:as both traiangles are homologous,
WX/XZ=VW/ ZY
WX= 52×10/8
ANSWER: a=12 b=15
Explanation: (look at work below)
4a + 1b = 63 (eq1)
5a + 3b = 105 (eq2)
-12a + -3b = -189 (subt. eq1 from eq2)
————————-
-7a = -84
a = 12
4(12) + 1b = 63 (plug in the a value)
48 + 1b = 63
b = 15
