Graph this solution -2x+4y=5

Question

I just need help getting the points to plot

Answer 1

Hi Jazmin,

If you want to graph -2x+4y=5 find at least 2 data points.

You choose the values for one of your variables and calculate the value for the other.

For example. I'll choose a value of 0 for x

-2(0) +4y =5

4y=5

y=4/5

so one data point is (0, 4/5) This is also the y intercept.

I'd then choose the value 0 for y and calculate x

-2x +r(0) = 5

-2x = 5

x=-5/2

so another data point would be (-5/2,0) this also is called the x-intercept.

Once you have 2 points, you can draw your line.

You can also choose a different number for x and solve for y.

Hope this helps :)
