What is the slope intercept form of an equation that goes through (-3,-5) and slope is 3/7
svet-max [94.6K]

Answer:

Step-by-step explanation:

Point slope form: y−7=34(x−3)

Slope intercept form: y=34x+194..or..y=34x+434

Explanation:

Since you have one point and the slope, you can use the point slope formula, then solve for y to get the slope intercept form, so that you can determine the y-intercept (b). Then you can graph the resulting equation.

Point slope formula

y−y1=m(x−x1), where x1,y1=(3,7), and m=34 is the slope.

Substitute the given values into the formula.

What is the fractional equivalent of 0.2323...? 23/99 23/999 2/9
lana [24]
It is equivalent to 23/99 but not for the rest.

As the denominator gets larger, the decimals gets smaller.
eg. 23/999 = 0.023232323...

As you can see , it is 0.02 now so it is not equivalent to 0.232323 as it is 0.2
