Step-by-step explanation: Slope-Intercept equations and graphs.

These are in y = mx + b form. M is slope. b is the y-intercept

For the y-intercept, you identify and label the place on the y-axis where the graphed line crosses it. That is one HINT to figuring out the equation that matches the graph. If the y-intercept is 0, there will be nothing after the 'x' term. If the y intercept ia any other number, that number will appear as a + or - after the 'x' term when you simplify the equation in y = mx + b form.

You have to draw the "stair steps" It helps you see slope. How many blocks up or down is the Rise. How many blocks from left to right is the Run.

Start by making a fraction Rise/Run if the Run is 1, the Slope is a whole number, the Numerator of the fraction (the 1 disappears from the equation).

If Colorado Springs, Colorado, has 1.2 times as many days of sunshine as Boston, Massachusetts, how many days of sunshine does e

Paul [167]

Colorado and Boston have 263 and 219 days of sunshine respectively.

<h3>What is the solution to the Equation?</h3>

Let the number of days of sunshine in Colorado is x and the number of days of sunshine in Boston is y.

Total number of days of sunshine=482

Also, the number of days of sunshine in Colorado is 1.2 times the number of days of sunshine in Boston.

So, the equation is formed as follows:

x+y=482 -(1)

The other equation is formed as:

x=1.2y -(2)

Substitute the value x from equation (2) in (1),

1.2y+y=482

2.2y=482

y=482/2.2

y=219

Substitute the value of y in equation (1),

x+219=482

x=482-219

x=263
