Hi there! I can help you! The slope-intercept formula is y = mx + b, where m = slope, b = y-intercept, and y and x remain unfilled. The formula for finding slope is y2 - y1 / x2 - x1, where you subtract the values of the first coordinate from the second coordinate. Let's use the points (26, -12) and (30, -24). Set it up like this:
-24 - (-12)/ 30 - 26
-24 + 12 is -12. 30 - 26 is 4. -12/4 is -3. The slope is -3. Now, let's solve for the y-intercept. 0 will be filled in as the x value. We will use one of the points on the line to help answer this question. Let's use the point (26, -12). The problem becomes -12 = -3(26) + b. Now, let's solve. -3 8 26 is - 78. Now, we add 78 to isolate the b. -12 + 78 is 66. There. b = 66. The formula for the table in y-intercept form is y = -3x + 66.

Answer:
Step-by-step explanation:
x^2/100 + y^2/25=1 -----(1)
Since 25<100
Hence the above equation is of the form x^2/a^2+ y^2/b^2=1-------(2)
Comparing (1) and (2)
a^2=100
a=10
Major axis=2a=20
Answer:
um I think its b
