Which equation represents the line that passes through the points (4, 6) and (−2, −1)?
KatRina [158]

Find the slope first by using rise/run

m=\frac{6-(-1)}{4-(-2)}\\m=\frac{6+1}{4+2}\\m=\frac{7}{6}

y=mx+b\\y=\frac{7}{6}x+b

We need to find the y-intercept. Substituting one of given ordered pairs. I will use (-2,-1).

Substitute x = -2 and y = -1 in the equation.

-1=\frac{7}{6}(-2)+b\\-1=\frac{7}{-3}+b\\-1=-\frac{7}{3}+b\\-1+\frac{7}{3}=b\\b=\frac{4}{3}

Thus the y-intercept is 4/3.

From y = mx+b, the equation is.

y=\frac{7}{6}x+\frac{4}{3}

A, B & C lie on a straight line.
Liono4ka [1.6K]

Answer:

x = 129°

Step-by-step explanation:

∠ ABD and ∠ DBC are a linear pair and sum to 180° , then

y + ∠ DBC = 180°

107° + ∠ DBC = 180° ( subtract 107° from both sides )

∠ DBC = 73°

the exterior angle of a triangle is equal to the sum of the 2 opposite interior angles , then

x = ∠ DBC + z = 73° + 56° = 129°

Which of the following are polynomial functions?
Vinil7 [7]

A polynomial function is a function involving only non-negative (positive and 0) integer powers of 'x', i.e. all terms with ' 'x' have a non-negative integer power, such as a quadratic x^{2} x^{3} and so on.

Option E is the answer.

Rest all are wrong answers. they do not have positive integers.
