Which of the following is the equation of a line in slope-intercept form for a line with slope = 5 and y-intercept at (0, -3)?

Answer

hello :

note : The equation of a linear function in point-slope form is  :                        y – y1 = m(x – x1)

The point is A (x1 , y1)

Step-by-step explanation:

in this exercice : m = 5       x1 = 0    y1 = -3

the equation of a line in slope-intercept form for a line is :

y - ( -3) = 5 ( x - 0)

y +3 = 5 ( x - 0)

Step-by-step explanation:

the equation of a line in slope-intercept form for a line with slope = 5 and y-intercept at (0, -3)

Slope intercept form of a line is

where m is the slope and b is the y intercept

given slope =5 and y intercept

now plug in the values in the slope intercept for

d) by the cross product property, ab^2 = bc multiplied by ad

step-by-step explanation:

we are given

in the given triangle abc

angle a is 90° and segment ad is perpendicular to segment bc

we can see that

triangle(abc) and triangle(abd) are similar because they have common side and same angle (90 degree)

so, triangles(abc) and abd are similar

since, they are similar

so, the ratio of their sides must be equal

we get

now, we can cross multiply

and we get

so, this could be step to prove it
