Write in slope intercept for slope being -5/7 and passes through (-4,-5)
frutty [35]

Answer:

y = -5/7x - 55/7

Step-by-step explanation:

Slope-Intercept Form: y = mx + b

Step 1: Define

Slope <em>m</em> = -5/7

Random point (-4, -5)

y = -5/7x + b

Step 2: Find y-intercept <em>b</em>

-5 = -5/7(-4) + b

-5 = 20/7 + b

b = -55/7

Step 3: Write linear equation

y = -5/7x - 55/7
