I’m so confused. explain your answer, !

y+2 = 3/4 (x-1)

Step-by-step explanation:

We have a slope and a point, we can use the point slope form of the equation for a line

y-y1 = m(x-x1)

where m is the slope and (x1,y1) is the point

y--2 = 3/4(x-1)

y+2 = 3/4 (x-1)

The equation for a line is written as Y - Y1 =  slope(x-X1)

You are given (1,-2) as a point, so x1 = 1 and y1 = -2 and the slope is given as 3/4

replace those values in the equation:

y - (-2) = 3/4(x-1)

When you have a minus and a negative number as above it becomes an addition.

The equation becomes:

y+2 = 3/4(x-1)

answer: .64
