Which of the following ratios is equivalent to 2:3? 12:13

14:21

20:25

1:4

14:21

Step-by-step explanation:

Think of it as equal fractions, if that helps.

Finding an equivalent fraction is the same as finding an equivalent ratio.

If you multiply both the numerator and denominator of 2/3 or 2:3 by the same number, you'd get an equivalent fraction/ratio.

2 multiplied by 7 is 14, 3 multiplied by 7 is 21. So, 2:3 and 14:21 are equivalent.

c. y = 1/4 x + 5

step-by-step explanation:

first, put the equation of the line on the graph into slope-intercept form

(y = mx + b):   y = -4x + 8

second, a perpendicular line has to have "an opposite/reciprocal slope" to the original slope. so, find the "m" value in your original equation (it's -4, right? )

original slope: m = -4   perpendicular slope: change the sign to its opposite and find the reciprocal ("flip" the number)

new slope is now positive (b/c the original slope was negative 4), and it's 1/4 (not the original slope of 4 or 4/1)

in the attachment.   i didn't see your choices.   the word which means there is choices.

step-by-step explanation:

(x,y)

x tells you how much left or right you go from the origin

y tells you how much down or up you go from the origin

so for example (-3,2), you go left 3 and up twice. i denoted which of the ordered pairs is which in my graph.
