Answer:
x=4
Step-by-step explanation:
3(3x+2)=7(x+2) Cross product
9x+6=7x+14 Solve for x
9x-7x=14-6
2x=8
x=8/2
x=4
Answer:
y=2/3x - 6
Step-by-step explanation:
use the formula y=mx+b. the m of this equation is equal to the slope and you know that the slope is 2/3. the b of the equation is equal to the y-intercept so, to find b you simply look at the points given. the points are written in (x,y) form so if -14 is x, -6 must be y. remember to KEEP CHANGE CHANGE your signs so that plus sign becomes negative 6. Hope this helps!
