The equation of line in point-slope form of the line that passes through the point (−1, −3) and has a slope of 4 is:
y+3=4(x+1)
Step-by-step explanation:
Given
m=4
and
Point = (x1,y1) = (-1,-3)
The general form of point-slope equation of line is:
Hence,

Answer:
A
Step-by-step explanation:
The diagonals of a parallelogram bisect each other. Hence, the two shorter sides created on diagonal RT ("6x-7" and "x+28" ) are equal.
<em>We can set them equal and solve for x:</em>
<em></em>
<em />
<em>So the side length of 6x -7 is:</em>
<em>6(7)-7 = 35</em>
<em>and the side length of x + 28 is:</em>
<em>7 + 28 = 35</em>
<em />
<em>THus, the diagonal RT = 35 + 35 = 70 units</em>
<em />
<em>Answer choice A is right.</em>
