x y −5 0 0 5 2 7 Which linear equation represents this nonproportional linear relationship? (1 point) Responses y=−x+5 y equals negative x plus 5 y=15x+5 y equals Start Fraction 1 over 5 End Fraction x plus 5 y=−5x+5 y equals negative 5 x plus 5 y=x+5

Answer 1

y = x + 5

Answer 2

The table shows the number of parts, y , a machine produces each hour, x . Write an equation for this situation, and indicate if this is proportional or nonproportional. y (number of parts) x (number of hours) 0 0 125 1 250 2 375 3 500 4(1 point) Responses y=125x, proportional y equals 125 x , proportional y=125x+1, nonproportional y equals 125 x plus 1 , nonproportional y=125x, nonproportional y equals 125 x , nonproportional y=x+125, nonproportional y equals x plus 125 , nonproportional

Answer 3

y = 125x, proportional

Answer 4

Write y−6x=5 in slope-intercept form(1 point)

Answer 5

To write the equation y - 6x = 5 in slope-intercept form, first isolate y:

y = 6x + 5

Therefore, the equation in slope-intercept form is y = 6x + 5.

Answer 6

Answer 7

In mathematics, a proportion is an equation that states that two ratios are equal. In other words, two fractions are proportional if their cross-products are equal.

For example:
2/3 = 4/6

In this case, the proportions hold true because both ratios reduce to the same value, making them equal.
