A student says that the x-intercept of a line is (0,-10,). Is the student correct? Explain.

nataly862011 [7]

Answer:

Yes, the student is correct

Step-by-step explanation:

Given

$(0,-10)$

Required

Does it represent the x intercept

At the x intercept, the value of x is 0.

So, the function $(x,y)$ becomes $(0,y)$

$(0,-10)$ can be compared to $(0,y)$

Hence, the student is correct

Which of the following is the equation of a line perpendicular to the line

Taya2010 [7]

Answer:

A. - 2x + 3y = 21

Step-by-step explanation:

The perpendicular lines have opposite reciprocal slopes.

The given line has a slope of:

m = -3/2

The perpendicular slope is:

m = 2/3

And its y-intercept is:

9 = 2/3*3 + b
b = 7

The line is:

y = 2/3x + 7

Convert this into standard form and compare with answer choices:

3y = 2x + 21
- 2x + 3y = 21

Correct choice is A

Answer:

The correct option is 3.

Step-by-step explanation:

From the given graph it is noticed that the related line passing through the point (-3,1) and (0,3).

If a line passing through two points, then the equation of line is

$y-y_1=\frac{y_2-y_1}{x_2-x_1}(x-x_1)$

The equation of related line is

$y-1=\frac{3-1}{0-(-3)}(x-(-3))$

$y-1=\frac{2}{3}(x+3)$

$y-1=\frac{2}{3}(x)+2$

Add 1 on both the sides.

$y=\frac{2}{3}(x)+2+1$

$y=\frac{2}{3}(x)+3$

The equation of related line is $y=\frac{2}{3}(x)+3$ .

The related line is a dotted line, it means the point on the line does not included in the solution set.

The shaded region is above the line so the sign of inequity is >.

The required inequality is

$y>\frac{2}{3}(x)+3$

Therefore option 3 is correct.
