Y = 8

Explanation:

X = 10

5x - 4y = 18

5(10) - 4y = 18

50 - 4y = 18

50 - 4y = 18
-50 -50

-4y = -32

-4y/-4 = -32/-4

y = 8

M = 2/3, B = -5<br> M = -5, b = 3/2<br> M = 2, b = -6<br> M = -5, b= 2
MA_775_DIABLO [31]

Answer: m = 3/2, b = -5

Step-by-step explanation:

When we input these values into slope-intercept form y = mx + b, then we get y = 3/2x -5. When trying out different x values, we get the same points that are on the line such as (2, -2) also the y-intercept is -5, so we know it is a true statement and that the slope 3/2 and y-intercept -5 are the only correct answers for this line.
