Ok so
basically solve for y
2x+18y=36
subtract 2x from both sides
18y=-2x+36
divide both sides b 18
y=-1/9x+2
Answer:
It's A. (2, 0) and (0, -4)

Answer:
- slope: 6; y-intercept: -3
- slope: 11; y-intercept: -1
- slope: 2; y-intercept: -13
- slope: 1; y-intercept: -6
Step-by-step explanation:
The slope is found using the slope formula. It works well to choose ordered pairs that only differ by 1 in their x-value.
m = (y2 -y1)/(x2 -x1)
The y-intercept is the y-value when x=0. If it is not in the table, it can be found from one point and the slope.
b = y1 -m·x1
__
1) slope = (9 -3)/(2 -1) = 6
y-intercept = -9 -6(-1) = -3
__
2) slope = (21 -(-1))/(2 -0) = 22/2 = 11
y-intercept = -1 . . . from table for x=0
__
3) slope = (-9-(-11))/(2-1) = 2
y-intercept = -11 -(2)(1) = -13
__
4) slope = (-4 -(-5))/(2 -1) = 1
y-intercept = -7 -1(-1) = -6
45 sq feet. Split the irregular shape into two regular shapes then follow the formula length times width for each rectangle, then add the products together to get the total area for the irregular figure
