Answer: all of them are x,y
Step-by-step explanation:
Like a first step bc. there is a denominator this will be more usefully eliminate it so what you can make it multiplied both sides by 2
- so will get
-2/2x +2*3/2 = 2(-4x+7)/2
(-2x +6)/2 = 2(-4x+7)/2 common denominator the 2 so make the numerators equal and solve for x
-2x+6=-8x+14
6x=8
hope helped
Answer:
1. is 25
2. I think this one is 25 too?
Step-by-step explanation:
im working on the second
Slope = (10 - 5)/(-9 + 15) = 5/6
y = mx + b where m = slope and b = y-intercept
b = y - mx
b = 5 - (5/6) (-15)
b = 5 +12.5
b = 17.5
Equation y = 5/6 x + 17.5
Y-intercept = 17.5
X-intercept when y = 0
So
5/6 x + 17.5 = 0
5/6 x = -17.5
x = (-17.5) (6/5)
x = -21
Answer
Y intercept (0, 17.5 )
X intercept (-21 , 0)
