Sagot :
Answer:
The slope of the line is m = 2.
The y-intercept is (0,7).
The equation of the line in the slope-intercept form is y = 2 x - 7.
Step-by-step explanation:
The slope of a line passing through two points [tex]P = \left(x_{1}, y_{1}\right)[/tex] and [tex]Q = \left(x_{2}, y_{2}\right)[/tex]
is given by [tex]m=\frac{y_{2}-y_{1} }{x_{2} -x_{1} }[/tex]
We have that [tex]x_{1} = 6[/tex] , [tex]y_{1} = 5y[/tex] , and [tex]y_{2} =7.[/tex]
Plug the given values into the formula for a slope: [tex]m=\frac{7-5}{7-6} =2[/tex].
Now, the y-intercept is [tex]b=y_{1} -mx_{1}[/tex] (or [tex]b =y_{2} -mx_{2}[/tex], the result is the same).
[tex]b=5-(2)*(6)=-7[/tex]
Finally, the equation of the line can be written in the form [tex]y=b+mx[/tex]:
[tex]y=2x-7[/tex]
Answer:
- [tex]\Large\boxed{\sf{y=2x-7}}[/tex]
Step-by-step explanation:
The slope formula is used to find the equation of the line that passes through the points in this problem.
SLOPE FORMULA:
[tex]\Longrightarrow: \sf{\dfrac{y_2-y_1}{x_2-x_1}=\dfrac{RISE}{RUN} }[/tex]
- y₂=7
- y₁=5
- x₂=7
- x₁=6
[tex]\Longrightarrow: \sf{\dfrac{7-5}{7-6}=\dfrac{2}{1}=2 }[/tex]
Use the slope-intercept form.
SLOPE-INTERCEPT FORM:
[tex]\Longrightarrow: \sf{Y=MX+B}[/tex]
[tex]\Longrightarrow: \text{The M represents the "slope".}[/tex]
[tex]\Longrightarrow: \text{The B represents the "y-intercept".}[/tex]
y=2x-7
- Therefore, the slope is 2 and the y-intercept is 7.
- The correct answer is y=2x-7.
