Answer:
The answer is Dilation of a scale factor of 4 followed by a reflection of the y axis.
Step-by-step explanation:
On the smaller triangle, the line EF has a length of 1 unit.
On the larger triangle, the line EF has a length of 4 units.
Therefore, the smaller triangle was dilated by 4, since 4x1 is 4.
The triangles was flipped over the y axis.
This means that it was reflected over the y axis.
Answer:

Step-by-step explanation:
Your equation is in slope-intercept form, y = mx + b, where m is the slope and b is the y-intercept. Your line has a slope of 7. In order to find the line perpendicular to this line, we have to take the opposite reciprocal of the slope. The perpendicular slope to m = 7 is m = -1/7. Now we go through x = -5 and y = 6 to find the new equation.
6 = -1/7(-5) + b gives us
6 = 5/7 + b and
b = 37/7
Therefore, the equation of the line perpendicular to your original line is
