To graph you first need to solve Find your x and y You need to get you y by its self to do that you subtract 12x on both side it will look like this 12x +9y=15 -12x. -12x 9y=-12x+15 you are now left with y on the left ( you don't really get ride of the number you just move it to the other side and and because the 12 was + it now becomes a -) 9y=12x+15 Now you need to get y completely by its self by division 9y=12x+15 /9 /9 Y = 1.3x+15 Now plug you y in your equation 12x+9(1.3+15)=15 12x+11.7+135=15 12x+146=15 -146 -146 12x = -131 /12x /12x X= -10.9 12(-10.9) +9y=15 -13.8 + 9y =15 +13.8. +13.8 9y = 18.8 /9. /9 Y= 2.08 So now that you have you x and y you can graph you two points (10.9, 2.08)

Answer from: zhellyyyyy

12x+9(1.3+15)=15 12x+11.7+135=15 12x+146=15 -146 -146 12x = -131 /12x /12x X= -10.9 12(-10.9) +9y=15 -13.8 + 9y =15 +13.8. +13.8 9y = 18.8 /9. /9 Y= 2.08 hope i helped

Answer from: Quest

x=-2

infinite number of lines, so there is an infinite number of equations.

step-by-step explanation:

there are an infinite number of line that passes through the point (-2,5)

x=-2 is one line that passes through the point

y = 5 is another line that passes through the point

(these two lines are perpendicular to each other).

since the number of numbers are infinite and the slope is the ratio of two numbers,(change in y over change in x) we can have an infinite number of slopes. our only condition is that it passes through the point (-2,5)

A. write an equation of a line that passes through (-2, 5). b. how many different equations could y

Answer from: Quest

step-by-step explanation:

f(x)=2x^2 -1

translation is a function transformation that transform the function in a way of translating. by translating the function its graph is moved up an down. moving the function f(x) 2 units to the left will be the new function g(x) with the equation: g(x)=f(x+2)=2(x+2)^2 -1
