it's asking to write an equation in slope-intercept form for the line with slope -4 and y-intercept 7. then graph the line. plea
LuckyWell [14K]

Answer:

Equation = y = -4x+7

See the graph below

Step-by-step explanation:

The equation of the line in slope intercept form is expressed as;

y = mx+c

Given

slope m = -4

y-intercept c = 7

Substitute

y = -4x + 7

Get the x intercept.

at y = 0

0 = -4x + 7

4x = 7

x = 7/4

x = 1.75

The x coordinate  (1.75, 0)

Get the y intercept

at x = 0;

y = -4(0)+7

y = 0+7

y = 7

The y coordinate is (0, 7)

Answer: 0.25

<u>Step-by-step explanation:</u>

You need to convert the cm³ into m³

\frac{250,000(cm)(cm)(cm)}{}* \frac{1(m)}{100(cm)} * \frac{1(m)}{100(cm)}* \frac{1(m)}{100(cm)} = \frac{250,000m^{3}}{1,000,000}

= .25 m³ per m²
