Answer:

y=5/2x+3 or y=\frac{5}{2}x+3

Step-by-step explanation:

<u>Step 1:</u>

Compute the slope (-4, -7), (2,8):

m=5/2

<u>Step 2:</u>

Compute the y intercept:

b=3

<u>Step 3:</u>

Add the results together:

y=5/2x+3 or y=\frac{5}{2}x+3

Hence, the final answer is y=5/2x+3 or y=\frac{5}{2}x+3

<em>Greetings from Brasil...</em>

One way to solve this question is through determinant

| X     Y     1 |

| X₁    Y₁    1 |  = 0

| X₂    Y₂   1 |

We have:

(X₁; Y₁) = (-4; -7)

(X₂; Y₂) = (2; 8)

then

| X   Y   1 |

| -4  -7   1 |  = 0

| 2   8    1 |

<h3>- 15X + 6Y - 18 = 0</h3>
