What is the equations of the line passing through points (-3,7) and (9,-1)?

The slope-intercept form:

m - slope

b - y-intercept

The formula of a slope:

We have the points (-3, 7) and (9, -1). Substitute:

Therefore we have

Put the coordinates of the point (-3, 7) to the equation of a line:

             subtract 2 from both sides

last option: rhombus or kite

step-by-step explanation:

a kite and rhombus have the same shape. as we don't have any specific formula for the calculation of area of kite. the diagonals are used to calculate the area of a kite or rhombus.

the formula for area of rhombus is given by:

here, d_1 is the first diagonal and d_2 is the second diagonal.

so,

last option is the correct answer ..
