Consider the these two linear equations: 10x + 5y = 90
y = ax + 18
What value of a will make the two lines parallel?

  a = -2

Step-by-step explanation:

The first equation can be rewritten in slope-intercept form:

  5y = -10x +90

  y = -2x +18

The value a=-2 will make the second line identical to the first.

answer: standard form is ax^2 + bx + c = 0

step-by-step explanation:

standard form is ax^2 + bx + c = 0

(2x + 1)(x - 2) = 0

distribute to get into standard form

2x^2 - 4x + x - 2 = 0

2x^2 - 3x - 2 = 0

a = 2, b= -3, c = -2

a is your answer
