Find the intercepts of the line that contains each pair of points (-1,-4) (6,10)

For the linear equation that contains the points (-1,-4) and (6,10), we have that:

A linear function is modeled by:

In which:

In this problem, it has points (-1,-4) and (6,10), hence, considering the slope is given by change in y divided by change in x, we have that:

Then:

Point (6,10) means that when x = 6, y = 10, and this is used to find b.

The function is:

The y-intercept is y = -2.

For the x-intercept, we have that:

The x-intercept is x = 1.

answer: cos [   arcsin (3/5) - arccos (1/2) ] =

step-by-step explanation: × = 3/5 = 0.6--> x = 36.87 and x = 180 - 36.87 = 143.13 deg

cos y = 1/2 --> y = +- 60 deg a. cos (x - y) = cos (143.13 - 60) = cos 83,13  

=

0.12

b. cos (36.87 - 60) = cos (-23.23) = 0.92
