Find three points and then graph: y 3/4x-1

Sagot :

anijlin
y = 3/4x - 1
to find points, plug in a value for x and solve for the y. 

i'm going to start with x =4, and solve for a y

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

The point is (4,2)

Find two other values by choosing two other x values and then you can graph the line

Hope this helps!

[tex] y= \frac{3}{4}x-1\\\\y=0\ \ \to\ \ \frac{3}{4}x-1=0\ \ | \ add\ 1\ to\ both\ sides\\\\ \frac{3} {4}x=1\ \ | \ multiply\ both\ sides\ by\ \frac{4}{3} \\\\x= \frac{4}{3}\\( \frac{4}{3},0)\\\\ x=0\ \ \to\ \ y= \frac{3}{4}*0-1=-1\\(0,-1) [/tex]
