Converted to a decimal it’s -0.8
5x + 4y = 32 ⇒ 45x + 36y = 288
9x - 1y = 33 ⇒ <u>45x - 5y = 165</u>
<u>41y</u> = <u>123</u>
41 41
y = 3
5x + 4(3) = 32
5x + 12 = 32
<u> - 12 - 12</u>
<u>5x</u> = <u>20</u>
5 5
x = 4
(x, y) = (4, 3)
To get slope use
y2 - y1 / x2 - x1
10 - 8 / 1 - 0 = 2/1 = 2
Slope = 2
The y-intercept is the coordinate point that has 0 as the x value.
(0, 8) is the y-intercept.
