Answer: y = -3x - 21

Explanation:

Slope intercept form: y = mx + b

m is the slope, and b is the y-intercept.

y + 8 = -3(x + 7)

Start by distributing -3 into the parenthesis.

y + 8 = -3x - 21

subtract 8 from both sides to get the final answer.

y = -3x - 29

Answer:

Slope-intercept form,

  • y = -3x - 29

Explanation:

Now we have to,

Rewrite the given equation in the slope-intercept form.

The slope-intercept form is,

→ y = mx + b

The equation is,

→ y + 8 = -3(x + 7)

Then the value of y will be,

→ y + 8 = -3(x + 7)

→ y + 8 = -3x - 21

→ y = -3x - 21 - 8

→ [ y = -3x - 29 ]

Hence, answer is y = -3x - 29.
