Since the congruent operator is ≅ and since AD is congruent to BD, I'm going to assume that you want to prove that AD is congruent to BD.
1. DE is equal to CD by definition since D is the midpoint of CE.
2. AE is equal to BC since opposite sides of a rectangle are equal to each other.
3. Angle AEC is equal to Angle BCE since all angles in a rectangle are right angles and all right angles are equal to each other.
4. Triangles ADE and BDC are congruent to each other because we have SAS congruence for both triangles.
5. AD is congruent to BC since they're corresponding sides of congruent triangles.
Answer:
The equation of line through (-3,1) and slope 2 in slope-intercept form is: y = 2x+7
Step-by-step explanation:
The slope-intercept form of an equation is given by:

here m is the slope of the line and b is the y-intercept
Given

Putting m=2 in the general form

In order to find the y-intercept, the given point (-3,1) will be substituted in the equation
So

Putting the value of b

Hence,
The equation of line through (-3,1) and slope 2 in slope-intercept form is: y = 2x+7
Answer:
T=14
Step-by-step explanation:
Isolate the variable by dividing each side by factors that don't contain the variable.
