Answer: Use the formula to plot the graph as explained below.

Explanation:

Using the slope-intercept form y=mx+b for your equation y= -5x+7

We can tell that the y-intercept occurs at (0,7)

The slope is -5, so you count 1 (right) on the x-axis for every -5 (down) on the y-axis.

Using that we can plot (1,2) and 2,-3) as shown in the graph below.

Answer:

See below.

Explanation:

It's a slope-intercept equation in the format of y = mx + b.

M = slope.

B = y-intercept.

Looking at this equation: y = -5x + 7.

We can see that -5 is the slope and 7 is the y-intercept.

So to graph, we start at the origin where x = 0 and plot the first point down which is always the y-intercept.

So

1st point ----> (0, 7)

Now to use the slope as x depends on y.

It increases by 5 each time.

Lets find the first 3 points.

1: (0, 7)

2: (1, 12)

3: (2, 17)

Thanks,
Eddie
