Line CD passes through points C(1, 3) and D(4, -3). If the equation of the line is written in slope-intercept form, y = mx + b,
what is the value of b?
-5
-2
1
5

5

Step-by-step explanation:

Since, the equation of the line passes through and is,

Thus, the equation of the line passes through points C(1, 3) and D(4, -3) is,

Now, the slope-intercept form of line is, y = mx + b,

By comparing,

b = 5

LAST option is correct.

option D is correct

b = 5

Step-by-step explanation:

Given that:

Line CD passes through points C(1, 3) and D(4, –3).

Find slope CD(m):

Formula for slope:

Substitute the given points we have;

then;

Substitute the point (1, 3)  to solve for b;

3 = -2(1) +b

3 = -2+b

Add 2 to both sides we have;

5= b

or

b = 5

An equation of line CD in slope-intercept form is;

Therefore, the value of b is, 5

option D is correct

b = 5

Step-by-step explanation:

Given that:

Line CD passes through points C(1, 3) and D(4, –3).

Find slope CD(m):

Formula for slope:

Substitute the given points we have;

then;

Substitute the point (1, 3)  to solve for b;

3 = -2(1) +b

3 = -2+b

Add 2 to both sides we have;

5= b

or

b = 5

An equation of line CD in slope-intercept form is;

Therefore, the value of b is, 5
