Question

What is the answer to questions 4-6? Please help

Answer 1

Answer:

4- y= -2+1

5- y=-5

6- y= -1/2x+4

Answer 2

Answer:

Step-by-step explanation:

Slope intercept form of a line passing through points $\left ( x_1,y_1 \right )\,,\,\left ( x_2,y_2 \right )$ is given by $y=mx+b$ where b is the y-intercept i.e, point at which the line intersects the y-axis , m represents the slope given by $m=\frac{y_2-y_1}{x_2-x_1}$

4.

b = 1

$m=\frac{y_2-y_1}{x_2-x_1}=\frac{-1-5}{-1-2}=\frac{-6}{-3}=2$

Equation is  y=2x+1

5.

b = - 5

m = 0 as the line is parallel to x - axis

Equation is y = - 5

6.

b = 4

$m=\frac{y_2-y_1}{x_2-x_1}=\frac{2-4}{4-0}=\frac{-2}{4}=\frac{-1}{2}\\y=\frac{-x}{2}+4$

Equation is $y=\frac{-x}{2}+4$
