When we were building our house, there were several things that we used math and geometry for.
Probably not a lot of graphing lines and etc. However, one could imagine especially linear calculations. For example, say you need 1 truck load of wood to build 1 house, how many truck loads of wood to build 3 houses? Or, based on the spacing of boards and etc, one would have to calculate the quantity of decking to cover a whole deck. This often requires calculations of areas, adjusting for odd shapes and angles, waste, and etc.
We would frequently use a "3-4-5 Triangle" to make things square. And there were some tricky calculations to make our roofline correct using rafters and a sloped roof.

How can you use intercept form?
You can use intercept form to graph and write quadratic functions. y=a(x-p)(x-q) You can also use intercept form to graph and write cubic functions. y=a(x-p)(x-q)(x-r)
When should you use the slope-intercept form?
When you are trying to graph an equation.
What is the y-intercept in this graph?
This question cannot be answered because there is no graph to tell where the y-intercept is.
Can you use a graph to write the equation of the line in slope-intercept form?
Yes
What is intercepting graphs and tables?
Intercept for a graph are points at which the graph crosses either axis. There is no such thing as an intercept for tables.

How do you find the coordinates of y-intercept and x-intercept on a graph?
You can either measure or estimate the coordinates visually from the graph, or solve the equation underlying the graph.
What is the x intercept on a graph?
It is found on the horizontal x axis number line on a graph whereas the y intercept is found on the vertical number line on a graph.
What is the y-intercept of the graph of 4x 2y 12?
The y-intercept of the graph of 4x + 2y =12 is probably 6
What happens to a line when the y-intercept is changed?
as the y-intercept increases, the graph of the line shifts up. as the y-intercept decreases, the graph of the line shifts down.
What statement is true about a graph of an inversely proportional relationship there is no x intercept and no y intercept there is only a x intercept there is only a y intercept or there is both x an?
The graph doesn't intersect either axis.
How do you find x and y intercepts?
if you are looking at a graph the y intercept is when the graph crosses the y axis and the x intercept is when the graph crosses the x axis. if you have a formula... plug zero in for x to find the y intercept, and plug zero in for y to find the x intercept
How do you use the y-intercept to graph a line?
The y-intercept identifies one point on a line. You need at least two points to determine a straight line.
