Slope-intercept form: y = mx + b

m = the slope

b = y-intercept.

In this problem,

m = 3/5

b = ?

So far y = 3/5x + b

Let's plug the point (-3, -1) into our slope equation.

-1 = 3/5(-3) + b

Simplify the right side.

-1 = -9/5 + b

Add 9/5 to both sides.

4/5 = b

The equation is: y = 3/5x + 4/5

Answer choice A is correct.

Find m. Please guys I really need your help :(

Answer:

m=\sqrt{2} inches

Step-by-step explanation:

From the diagram, it is given that the triangle is a right angle isosceles triangle (angles are 45°, 45° and 90°). This means that the two shorter sides of the triangle are equal in length and that the side m can be found by using the Pythagorean theorem a^{2}+b^{2}=c^{2}.

m^{2}+m^{2}=2^{2} (The two shorter sides of the triangle are equivalent)

2m^{2}=4

m^{2}=2

m=\sqrt{2} inches

I hope this helps :)

Evaluate when x = 2<br> -X2 + 5x - 7
Rufina [12.5K]

Answer:

Step-by-step explanation:

f(x)=x²-5x+7

f(2)=2²-5.2+7=4-10+7=11-10=1

f(-1)=(-1)²-5.(-1)+7=1+5+7=13

f(1/3)=(1/3)²-5(1/3)+7=1/9-5/3+7=49/9

∴, f(2)-f(-1)+f(1/3)

=1-13+49/9

=58/9-13

=-59/9
