Convert the equations from standard from slope-intercept form.
2x-y = -7

Step-by-step explanation:

2x-y=2 is in standard form

(3,4) is a point on the line

y=mx+b is slope-intercept form, where m is the slope and b is the y-intercept

y=2x-2 is in slope-intercept form

y-y1=m(x-x1) is point-slope form, where m is the slope and (x1,y1) is a point on the line

y-4=2(x-3) is in point-slope form

d 192

step-by-step explanation:

we find our area to find area we multiply thoses numbers to get our answer so our area is 192

the equation for this situation is y=122+45. to solve the equation you would add 45 and 122 to get a total of 167lbs. in conclusion, grace's weight eight weeks ago was 167lbs.
