Answer:
-26 is the y-intercept
Step-by-step explanation:
since you already have the slope solved, you just have to plug in one of the two coordinate pairs. i plugged it (4,6) since it didnt have any negatives to work with. 6 should be where y is and 4 is x. you now should solve it as a normal equation. it gave me -26.
Answer:
2 or 8is the answer..............
Answer:
1. x = 2 y = 1
2. x = 17 y = 29/3
Step-by-step explanation:
1. Use elimination
-4x+3y=-5
4x-5y=3
x's cancel, so add them
-2y = -2
y = 1
substitute
4x -5(1) = 3
4x - 5 = 3
4x = 8
x = 2
2. Use elimination
2x+3y=36
10x-6y=12
Multiply top equasion by 5
10x+30y = 360
10x-6y = 12
x's cancel so subract
36y = 348
y = 29/3
Substitute
2x+3(2/3)=36
2x+2 = 36
2x = 34
x = 17
