(-3,0);slope=2/3 slope intercept form

Step2247 [10]

Y = mx + b, m = slope and b = y-intercept

Because you don't have the y-intercept, you take the equation and replace x and y with the values given, then solve for b and replace b in the original equation with the value found.

y = 2/3x + b
0 = (2/3)(-3) + b
0 = -2 + b
2 = b

y = 2/3x + 2 is the answer

Solve the system by substitution. x – 4y = -8 5у – 1 = x Submit Answer

Vikki [24]

Answer:

y = -7 and x = -36

Step-by-step explanation:

x - 4y = -8

5y - 1 = x

→ Substitute 5y - 1 into x - 4y = -8

5y - 1 - 4y = -8

→ Simplify
