Question

I don't have many points but I will give all my points can someone tell me the answer for both pls​

Answer 1

• 50. B
• 51. -3x + y = 11

Explanation:

50......................................................................

Parallel lines have equal slopes.

Converting the given into slope-intercept form:

• 2x + 3y = 15
• 3y = -2x + 15
• y = -2/3x + 5

Option B is the parallel line with different y-intercept

51.......................................................................

Perpendicular lines have negative reciprocal slopes.

Converting the given into slope-intercept form:

• x + 3y = 15
• 3y = -x + 15
• y = -1/3x + 5

Perpendicular line will have a slope of

• m*(-1/3) = - 1
• m = 3

The equation will be:

• y = 3x + b

to find b using the given point (-2. 5)

• 5 = 3*(-2) + b
• 5 = -6 + b
• 5 + 6 = b
• b = 11

So the line is:

• y = 3x + 11

or

• -3x + y = 11 in standard form
