PLZZ HEPPP A line passes through (−1, 5) and (1, 3). Which answer is the equation of the line? x + 2y = 7 x + y = 4 x + 2y = 5 x + y = 2

B.

Step-by-step explanation:

Again, to find the equation of the line, we need to find the slope and y-intercept. First, let's find the slope. Let (-1,5) be x₁ and y₁ respectively and (1,3) be x₂ and y₂, respectively. So:

So the slope is -1.

Now, to find the y-intercept, we can use the point-slope form. I'm going to keep using (-1,5) as the coordinate. Thus:

This is slope-intercept form. We want the answer to be in standard form, where:

A, B, and C are integers (and, conventionally, A is positive).

Thus, we need to rearrange the terms:

The answer is B.

hi there!

step-by-step explanation:

a roof pitch is basically for every inch rise there is 12 inches run.

the height of the roof is also known as the rafter.

formula: rafter^2 = rise^2 + run^2

rafter^2 = 5^2 + 12^2

rafter^2 = 25 + 144

rafter ^2 = 169"^2

the height of the roof from the lowest point to the highest point is 169"^2.

hope this : )
