Plsss help me graph this!!! Attached is the question
e-lub [12.9K]

The graph is a straight line graph with a slope of -1/2

Equation of a line in point-slope form

The equation of a line in point slope form is expressed as:

y - y₁ = m(x - x₁)

Given the following parameters

Point = (-2, 3)

Slope = -1/2

Substitute the given parameters into the formula

y-3 = -1/2(x-(-2))

y-3 = -1/2(x+2)

Write in slope-intercept form

2(y-3) = -(x+2)

2y-2(3) = -x -2

2y - 6 = -x -2

2y = -x + 4

y = -1/2x + 2

The graph of the equation is as shown below

To solve I would set up a ratio to visualize the question.

x in : 90 ft

1 in : 6ft

Then divide... 90 ÷ 6 = 15 ( this is the inches in the ratio that compares to 90 ft).

What expression represents the product of 3 less than twice x and 2 more than the quantity 3 times x?
Georgia [21]
"3 less than twice 'x' " . . . . that's (2x - 3)

" 2 more than the quantity (3 x) " . . . . . that's (3x + 2)

Their product is
                               (2x - 3) (3x + 2) .

If you want to expand it to a single expression, perform the multiplication,
and you have
                            6x² - 5x - 6  .
