Look at the scatterplot. which of these equations is the best representation of the trend line? y = -5x + 5 y = -5x - 5 y = 5x + 5 y = 5x - 5

we can look at the trend line, find the slope.

let's start at the start of the line, (0, 5).

the line goes up 5 units and goes right 1 unit, so that means the slope is 5/1, or 5.

so you know the slope is 5x. now let's see the y-intercept, ask yourself this, where is the start of the line ? we already answered that: (0, 5). so the y-intercept is 5.

the equation should look like y = 5x + 5, so the answer is C

the equation cos(35) =a/25 can be used to find the length of bc what is the length of bc? round to the nearest tenth
