Question

9.45x+7.65y=160.65 how do I graph this ???

Answer 1

So the first thing you have to do it to subtract 9.45x from 160.65. So do 160.65-9.45. Then once you do that, you have your x. So you can graph that number of the x line. Then you subtract 7.65 from 160.65. So 160.65-7.65. And then after you subtract that, you will then have your y value. So now you should have both your x and y, and you should be able to graph that! Hope I helped!

Answer 2

one way is to plot points

so we know that when x=0, the line crosses the y axis
and likewise, when y=0, the line crosses the x axis

one easy way is using that concept

so

first, set x=0 and solve for y (divide both sides by 7.65)
y=21
(0,21) is a point, aka the line crosses the y axis 21 units above the origin
to graph, start from the origin (intersection of x and y axis) and go up 21 units on the y axis and put a dot there


then set y=0 and solve for x (divide both sides by 9.45)
x=17
(17,0) is a point, aka the line crosses the x axis 17 units to the right of the origin
to graph, start from the origin (intersection of x and y axis) and go left 17 units on the x axis and put a dot there

now connect those 2 dots to graph your line
