Y = -4x + 2
3x + 2y = 6 (or in y-intercept form y=-3/2x + 3)
2x - y = 7 equals y = 2x -7 in y-intercept form. This means that the line has a positive slope and therefore goes upwards. This cannot be a potential equation because the line shown is clearly pointing downwards.
y=5 indicates that the line is a horizontal line that neither points upwards or downwards. This cannot be a potential equation because the line is pointing downwards.
The only possible equations left are y= -4x + 2 and 3x + 2y = 6, both of which graph a line pointing downwards because their slopes are negative. Hope this helps!
Answer:
y=−1.2

Please mark me brainllest!!!!!!!!!!!!!!
A-b=8
2a+3b=51
2a-2b=16
2a+3b=51
Subtract both
-5b=-35
b is 7 and a is 15
Answer:
14/15
Step-by-step explanation:
You are adding fractions, so you need a common denominator.
The least common denominator (LCD) for 3 and 5 is 3 × 5 = 15.
Both denominators must become 15.
3/5 + 1/3 =
= 3/5 × 3/3 + 1/3 × 5/5
= 9/15 + 5/15
= 14/15
Answer: 14/15
