Write an equation of a line with the slope of 1 and y-intercept of 4
1 answer:
Answer (<u>assuming it can be in slope-intercept form)</u>:
y = x + 4
Step-by-step explanation:
With the given information, we can write the equation of the line in slope-intercept form. Use the slope-intercept formula, , and substitute values for
and
.
The , or the coefficient of the x-term, represents the slope, so substitute 1 in its place. The
represents the y-intercept, so substitute 4 in its place. This gives the following answer:
(Remember that the coefficient of the x-term, 1, is still there. However, instead of , we can just write it as
.)

Answer: 82 sq. units .
Step-by-step explanation:
Let A (9, −1), B (−1, 7), C(−5, 2), D(5, −6) are the vertices of rectangle.
Then we plot them on graph ( as provided in attachment)
Length = AB units [By distance formula :
]
units
Width = BC = units
Area = length x width
=
Hence, the area of the rectangle is 82 sq. units .
