Answer:

Step-by-step explanation:

A graph is only a function when there is only one y value for each x value.

A trick is to draw a line through some points on the x-axis, and if the line goes through more than one point. Then it is not a function. (See picture)

Sorry, not all the lines are straight, but you get the point. B is the only one that doesn't have more than one point on the lines I drew.

What is the equation perpendicular to y= -1/5x +3 and goes through the point (7,4)?

Sphinxa [80]

Answer:

y - 4 = 5(x - 7) or y = 5x - 31

Step-by-step explanation:

Slope-intercept form: y = mx + b (m = slope, b = y-intercept)

Point-slope form: y - y₁ = m(x - x₁) ((x₁, y₁) = known point, m = slope)

1. Slope: perpendicular to -1/5 --> 5 (negative reciprocal)

2. Insert knowns into equation: y - 4 = 5(x - 7)

3. Turn into point-slope form (assuming that is what we are looking for):

Multiply: y - 4 = 5x - 35

Subtract: y = 5x - 31

Answer:

Step-by-step explanation:

in parallelograms, the measure of reciprocal angles is equal to 180 because they are supplementary,

m<D = 110 so the measure of m<A which is reciprocal to m<D is equal to 70
