how would I graph a slope of 0.2 and a y intercept of 0.3?

Question

I know that y intercept is up and down, and the slope is rise (up)over run (across) , but I am confused because of the decimal format. Thank you, I asked mom but she doesn't know either, and I couldn't find examples in the book.

Answer 1

Y = mx + b, Y = 0.2x + 0.3.

When y = 0, x = -1.5. X-int.
When x = 0, y = 0.3. Y-int.
When x = 5, y = 1.3.
P1(-1.5,0), P2(0,0.3), P3(5,1.3).
Use the above points for graphing.

Answer 2

Please ignore the 3 points preceding my name.
