Answer :

Answer:

y = 2x + 125

Step-by-step explanation:

y = mx + c

c in this problem is $125.

It is the amount of money she has already saved, that is not going to change, so this is the y intercept.

She saves $2 every day, with the number of days being x.

So she saves $2 × x = 2x

2x is the gradient.

On your graph, your straight lien should run through 125 on the y-axis.

The line should have a gradient, or slope, of 2x.

Make sure to plot carefully, looking at the scale of the graph.

The equation is that the total amount Anna saves will be y = 2x + 125. And the graph of the line is drawn below.

What is a linear equation?

A connection between a number of variables results in a linear model when a graph is displayed. The variable will have a degree of one.

The linear equation is given as,

y = mx + c

Where m is the slope of the line and c is the y-intercept of the line.

Anna is saving to get a few keepsakes on a family excursion. She has previously saved $125, and she saves another $2 from her remittance consistently.

Let 'x' be the number of days and 'y' be the total cost. Then the equation is given as,

y = 2x + 125

The equation is that the total amount Anna saves will be y = 2x + 125. And the graph of the line is drawn below.
