To graph the equation 2x + 5y = 10, Zeplyn draws a line through the points (5, 0) and (0, What is the slope of the line represen
wariber [46]

Answer: -2/5

Step-by-step explanation:

To find the slope, we set the function use y = mx + b forms.

2x + 5y = 10

        5y = -2x + 10              Minus 2x in both side

           y = -2/5x + 10/5       Divide 5 from both side

           y = -2/5x + 2

In the y = mx + b, the m before variable x is always the slope, so -2/5 is the slope for 2x + 5y = 10.

Maths question on algebraic equations ​= due in 10 minutes
erma4kov [3.2K]

Answer:

108 degrees.

Step-by-step explanation:

2x + 16 = 3x - 12  (corresponding angles; AB parallel to CD).

16 + 12 = 3x - 2x

x = 28.

So the angle marked 3x - 12 = 3(28) - 12

= 72 degrees.

Angle y is adjacent to the angle so

y = 180 - 72

= 108 degrees.

Identify an equation in point-slope form for the line perpendicular to y = –4x – 1 that passes through (–2, 7).
Harlamova29_29 [7]
To get a perpendicular line, your slopes will equal -1 when multiplied...this means if we multiply - 4 x (1/4), we get out slope to use for the next step.

Y - Y1 = M(X - X1)    passes through (-2, 7)
Y - 7 = 1/4(X - (-2))
Y - 7 = 1/4(X + 2)
Y - 7 = 1/4X + 1/2
   +7              + 7
Y = 1/4X + 7.5
