Answer:

Step-by-step explanation:
The slope formula for a straight line is:

Where, 'm' is the slope and 'b' is the y-intercept.
To find the x-intercept of a line, we need to equal 'y' to zero, and then solve for 'x'. In this case we know that the x-intercept is 1, so we have the point (x1, y1)=(1,0). We are given a second point which is: (x0, y0)=(-2, 12).
To find the slope, we use the following formula:

Now, The equation of the line is: y - y0 = m(x-x0). Then, substituting the values of 'm', 'x0' and 'y0' we have that:

The equation of the line using the slope-intercept form is:

The two angles, when added, should form a straight line.
A. ∠RST and ∠RSV form the line VT
B. ∠RST and ∠TSU form the line RU
C. ∠RST and ∠VSU form opposite angles with each other
D. ∠TSU and ∠USV form the line VT
E. ∠TSU and ∠RSV form opposite angles with each other
So, the answers are A, B and D.
