Practice Problems Find slope(m) and Y-intercept(b)
Make sure to write in standard form, y = mx + b for each
problem
1. y = 7x + 9
2. y=-5x-2
3. y = 3x + 1

1. slope is 7 and y-intercept is 9

2.slope is -5 and y-intercept is -2

3. slope is 3 and y-intercept is 1

Step-by-step explanation:

The standard equation of a line in slope form is;

y=mx + b where m is the slope and b is the y intercept.

In question 1.

y=7x + 9

slope is 7 and y-intercept is 9

In question 2

y= -5x - 2

slope is -5 and y-intercept is -2

In question 3

y= 3x + 1

slope is 3 and y-intercept is 1

2. angles qrt and qst both measures 156 degrees.

step-by-step explanation:  

we have been given a diagram of a circle and we are told that measure of arc qvt is 156 degrees.  

we can see from our given diagram that angle qrt and angle qst subtends to arc qvt.

since we know that angles subtended by the same arc at the circumference are always equal.

by angle subtended by same arc theorem, measure of angle qrt and angle qst will be equal to the measure of arc qvt.

therefore, angles qrt and qst both measures 156 degrees and 2nd statement is the correct choice.
