What is the slope of the line passing through the points (3,5) and (-1,7)?

Maurinko [17]

-1/2

To find the slope of the line between two points, we use the equation (y2-y1)/(x2-x1)

Substitute the values given for the xs and ys:

(7-5)/(-1-3)

2/(-4)

simplify: -1/2

Answer:

$\huge\boxed{157 \ \ \text{degrees}}$

Step-by-step explanation:

In order to find the value of ∠EFB here, we have to note our angle relationships.

We know that ∠CFE is already 90°. We also know that ∠CFA is 90°. Angle ∠AFB is inside ∠CFA. Since we know the measure of ∠AFB, we can find the measure of ∠BFC.

$23 + x = 90\\\\x = 90-23\\\\x = 67$

Now that we know ∠CFE and ∠BFC, which together make ∠BFE, we can add these angles up.

$90+67=157$

Hope this helped!
