The graph of a linear function has a slope of 1/4 and passes through the point (1,3). What is the y-intercept of the function?

Vikki [24]

Answer:

Step-by-step explanation:

In slope intercept form, y = mx + b, the m is the slope, the b is the y intercept, and x and y can be subbed in from the point you are given of (1, 3). We are told the slope, so everything we have fills in like this:

$3=\frac{1}{4}(1)+b$

Now we just need to solve for b:

$3-\frac{1}{4}=b$ and

$\frac{12}{4}-\frac{1}{4}=b$ so

$b=\frac{11}{4}$

Identify all of the following solutions of square root of x minus 8 end root plus 8 equals x.

Anit [1.1K]

$\sqrt{x-8} +8=x \\ \sqrt{x-8} =x-8 \\ {( \sqrt{x-8} )}^{2} = {(x-8)}^{2} \\ x-8= x^{2} -16x+64 \\ x^{2} -16x-x+64+8=0 \\ x^{2} -17x+72=0$

$(x-8)(x-9)=0 \\ x-8=0 \ and \ x-9=0 \\ x=8 \ and \ x=9$
