Answer:

The given line y = -2x +30 is a straight line as it is written in the

form y = mx + b.

The graph of the line y = -2x +30 is also straight and attached below.

Step-by-step explanation:

Given the equation

y = -2x +30

We know that the slope-intercept form of the line equation is

y=mx+b

Where m is the slope and b is the y-intercept

  • The graph of y=mx+b is a straight line as it is the line equation.

Writing the equation in the slope-intercept form

y = -2x +30

y = mx + b

Thus,

m = -2

b = 30

Thus, the given line y = -2x +30 is a straight line as it is written in the

form y = mx + b.

The graph of the line y = -2x +30 is also straight and attached below.

How do you write linear equation graphs?
hoa [83]
<span>Identify the slope, m. This can be done by calculating the slope between two known points of the line using the slope formula.<span>Find the y-intercept. This can be done by substituting the slope and the coordinates of a point (x, y) on the line in the slope-intercept formula and then solve for b. hope this help</span></span>

Your test scores in one class are 79 and 85. What possible scores can you earn on your next test to have a test average between
mestny [16]

Multiply the average by the number of tests to find the total of the scores:

82 x 3 = 246

88 x 3 = 264

The total of the three tests would need to be between 246 and 264

The total of the first two tests is 79 + 85 = 164

Subtract the total of the first two from the totals above:

246 - 164 = 82

264 - 164 = 100

The score of the third test needs to be between 82 and 100
