Answer:

The equation of any straight line, called a linear equation, can be written as: y = mx + b, where m is the slope of the line and b is the y-intercept.

Step-by-step explanation:

The y-intercept of this line is the value of y at the point where the line crosses the y axis.

Answer:

A. (0, -3)

B. (0, 2)

Step-by-step explanation:

A. y>4x-3, This equation is similar to Intercept form only instead of the equal sign you have an inequality. There for we know that our Slope is up 4 over 1 and that our y-intercept is (0, -3).

B. This sequence is similar, our slope it going to be down 1 right one and our y-intercept is going to be (0, 2)

Compare the enumerators because they have the same denominator. 2 is large than 1 so 2/3 is larger than 1/3

A car rental agency charges $120 per week plus $.12 per mile driven. How many miles did you drive if the total charge is $162?

777dan777 [17]

$\boxed{y=120+0.12x}\\
\\
y=162\\
\\
120+0.12x=162\\
\\
0.12x=162-120\\
\\
0.12x=42\\
\\
x=\frac{42}{0.12}\\
\\
\boxed{\boxed{x=350 \ miles}}$
