Question

2x+3y=15 graph and solve for y first

Answer 1

Solve for y by isolating it on the left side.

Answer 2

y=-2/3 x +5

plug that in and you will get your graph

Answer 3

remember that slope is the part in front of the x... so here, slope is -2/3. That means the graph slopes up to the left, and it rises 2 for every 3 it goes to the left.

The y-intercept is the number at the end, in this case, 5. Notice that for x = 0, the x term disappears... and you are left with y = 5. So that point, (0,5) is where the line crosses the y axis.

The best approach is usually to start at that y intercept, and then extend the line left and right from that point using the rise/run slope.

Answer 4

Then find where the line crosses the x axis.
